MAGNETIC MALLET AND LASER FOR A MINIMALLY INVASIVE IMPLANTOLOGY: A FULL ARCH CASE REPORT
  • - Background: An 81-year-old patient undergoing treatment at the practice showed mobility of the upper elements remaining to support a removable resin prosthesis. The patient requested to rehabilitate the upper arch with a fixed type of prosthesis.
  • - Purpose: To show how the use of devices such as the Magnetic Mallet allows us to perform complex rehabilitations in less time and in a minimally invasive way.
  • - Methods: Considering the initial clinical situation, the patient’s request and her general health conditions, the extraction of the remaining dental elements, root residues and implants was proposed in the same operation, as was the subsequent use of the laser to erbium and the Magnetic Mallet for the preparation of the new implant sites and the insertion of eight implant fixtures. Considering the age of the patient and the complexity of the operation, it was agreed with her to perform the operation in a conscious sedation regime, requiring the intervention of an anesthetist specialist.
  • - Results: The use of tools such as the Magnetic Mallet and the laser resulted in the implementation of a therapy, normally considered traumatic, in a minimally invasive manner. The patient had no pain or other complications during the surgery. In the following days, she confirmed that she had not developed any edematous areas and that she had not had post-operative pain. She stated that she therefore did not need to take pain-relieving or anti-inflammatory drugs. In addition, it can be said that she did not have any infectious complications.
  • - Conclusions: It can therefore be concluded that the combined use of the laser and the Magnetic Mallet made it possible to perform complex therapies even in this patient who is admittedly fragile due to clinical history and a present systemic condition.

EFFECTS OF DIFFERENT LOADING PROTOCOLS ON THE BONE REMODELING VOLUME OF IMMEDIATE MAXILLARY SINGLE IMPLANTS: A 2- TO 3-YEAR FOLLOW-UP
  • - Background: Twenty-two patients were enrolled.
  • - Purpose: The purpose of this study was to assess the effect of different loading protocols (immediate or delayed) on bone volume remodeling of an immediate implant-supported single crown in the maxilla with a follow-up from 2 to 3 years.
  • - Methods: Patients presenting a failing tooth have been rehabilitated with implant-supported single crowns. Data of patients with a survey from 2 to 3 years after baseline surgery were retrospectively acquired. One implant per patient was randomly selected during data analysis and assigned to one of two predictor groups: the loading protocol, 9 immediate vs 13 delayed loading; and tooth position, 9 incisors vs 9 canines. Cumulative survival rates were recorded; loss of crestal bone volume was assessed with cone beam computed tomography (CBCT) by means of software that superimposed the preoperative and postoperative CBCT scan data (Matrix Laboratory) and by destascan software.
  • - Results: No postoperative complications or implant failures were recorded. Bone volume loss from the 2- to 3-year follow-up period ranged between 19.1% and 22.0%, without significant differences between the two loading protocols. Irrespective of the tooth site, intragroup analyses revealed the presence of significant differences between preoperative and postoperative time evaluations for all the analyzed groups and subgroups. Volumes at baseline (ranging between 0.546 cc and 0.553 cc) recorded significant loss of approximately 110 mm3 (P values ≤ .0001) for both loading protocols. The volume at the postoperative evaluation ranged between 0.428 cc and 0.442 cc. Considering tooth site in the analysis, the subgroups showed similar behaviors at the crestal bone level.
  • - Conclusions: This study attested that the loss of crestal bone around an immediate implant-supported single crown depended on neither the loading protocol nor the tooth site.

MAXILLARY AND MANDIBULAR SPLIT CREST TECHNIQUE WITH IMMEDIATE IMPLANT PLACEMENT: A 5-YEAR CONE BEAM RETROSPECTIVE STUDY
  • - Background: A total of 38 patients were retrospectively selected (23 women and 15 men). Six patients underwent ARST surgeries in both the maxilla and the mandible and were excluded from statistical analysis. Differences between 16 maxillae and 16 mandibles and between 12 single crowns and 20 fixed partial dentures (FPDs) were searched.
  • - Purpose: This study aimed to test the effectiveness and reliability of the alveolar ridge-splitting technique in atrophic posterior arches, investigating the middle-term volumetric and clinical outcomes.
  • - Methods: Atrophic alveolar ridges in the maxillary and mandibular posterior areas were treated with the alveolar ridge-splitting/expansion technique (ARST), immediate implant placement, collagen sponges covering the defect, and healing by secondary intention. Areas were rehabilitated by fixed dental prostheses supported by dental implants. Changes in volume and width of the alveolar ridge were retrospectively calculated by comparing the x-ray tomography scans obtained before and 5 years after surgery. Report of failure in the case sheets was taken into account. Cross-sectional images were also used to assess the thickness of the labial alveolar plates at the implant shoulder. Nonparametric analyses of variance with post hoc and pair-comparison tests were performed with a level of significance of .05.
  • - Results: Episodes of minor swelling occurred within the first 2 days after surgery. Neither mucositis nor flap dehiscence had been registered. The mean values of buccal cortical thickness were 2.46 ± 0.49 mm and 1.15 ± 0.33 mm, respectively, in the maxillary and mandibular areas. After 5 years of survey, maxillary increases in alveolar ridge width and volume were +4.4 ± 0.4 mm and +295 ± 45 mm3, respectively, whereas the same outcome variables (+3.5 ± 0.7 mm and +217 ± 53 mm3) measured in the mandible appeared to be significantly smaller than those in the maxilla (P < .0001). One maxillary single implant failed. Cumulative survival rates at 5 years were 100% for mandibles and 95.5% (95% CI: 86.8% to 100%) for maxillae.
  • - Conclusions: Posterior areas of the maxilla displayed a higher increase in alveolar width and volume than mandibular areas, and even if it would be premature to draw survival conclusions at this stage without any statistical support, a lower cumulative survival rate was reported for the maxillary single implants.

LATERAL DISPLACEMENT OF MAXILLARY SINUS PALATAL WALL: A 1-YEAR RETROSPECTIVE COMPUTERIZED TOMOGRAPHY STUDY
  • - Background: A total of 18 implants were selected for retrospective volumetric and linear analyses.
  • - Purpose: To examine the short-term outcomes of maxillary sinus augmentations consisting of laterally and apically displacing the palatal wall through a transcrestal approach.
  • - Methods: The maxillary sinus floor was fractured in its palatal aspect by allowing a displacement in the buccal and apical direction with a magnetoelectric system. A medial displacement of the alveolar crest in its palatal bony plate was performed at the same time. Crestal bone change was investigated using superimposed preoperative and postsurgical computed tomography scans. Clinical and radiologic outcomes over 1 year were evaluated.
  • - Results: Sinus floor and alveolar bone augmentation surgery led to a significant increase in the bone volume. No part of the implant apices appeared to protrude into the maxillary sinus at the 1-year follow-up. The width of the alveolar crest changed from 5.1 ± 0.5 mm to 6.5 ± 0.7 mm, with a significant increase of +1.4 ± 0.6 mm registered at 1 year.
  • - Conclusions: Significant and effective bone gains allowed proper placement of the dental implants but with a minimal loss of peri-implant bone volume.

CLINICAL AND RADIOGRAPHIC EVALUATION OF MODIFIED TRANSALVEOLAR TWO-STEP OSTEOTOME-MEDIATED LOCALIZED MAXILLARY SINUS ELEVATION: A RETROSPECTIVE COMPUTED TOMOGRAPHY STUDY WITH A 3-YEAR FOLLOW-UP
  • - Background: Forty patients were retrospectively selected. The preoperative height of the available alveolar bone was 2.9 ± 0.6 mm.
  • - Purpose: This study aimed to report a practicable and noninvasive two-stage technique for sinus elevation and delayed implant insertion in the augmented site with residual bone height down to 3 mm or even lower.
  • - Methods: The surgical technique employed a two-stage process for rehabilitation of posterior maxillary single-tooth edentulous areas, involving, in the first step, transcrestal maxillary sinus floor augmentation with a collagen sponge to fill the intrabony cavity resulting from the detachment of the sinus membrane; the second step consisted of another indirect sinus floor elevation using magnetoelectric surgery with immediate implant placement and no grafting material.
  • - Results: A significant increase in bone height (P < .01) was found for both the first and the second surgery. The overall bone height was measured at 3 years after the first surgery. Measurements of the bone height ranked for tooth positions showed no significant difference between premolars and molars. None of the selected patients registered an implant failure.
  • - Conclusions: Two-stage osteotome-mediated sinus elevation appeared to be a predictable technique that enabled practitioners to increase the bone height and to obtain successful outcomes even if the amount of bone was approximately 3 mm in height.

FIRST LOOK AT A NEW TECHNOLOGY THAT MAY SIMPLIFY ORAL SURGERY
  • - Background: Many dentists accomplishing surgical procedures (such as tooth extractions, implants, sinus lift procedures and impacted tooth removal) use rotary or hand instruments to remove bone. Can these procedures be accomplished with more adequate vision, easier, safer, and with more comfort for the patient? The Magnetic Mallet uses electromagnetic forces and provides high-intensity impact to bone facilitating bone remodeling and removal. The Magnetic Mallet by Osseotouch is a novel technology that is among the most innovative that CR has recently seen.
  • - Purpose: Clinicians Report's team of Scientists, CR Clinicians, surveyed users, and ultimately an oral surgeon tested and reviewed the Magnetic Mallet to give a first clinical look at its pros and cons and determine whether the Magnetic Mallet can offer a better experience for both the dentist and the patient.
  • - Methods: The Magnetic Mallet is used in complex extraction procedures, which are among the most challenging procedures accomplished in a dental office. Extraction procedures often start and end without a glitch; however, unexpected challenges arise. Surgeons are always looking for better instruments and better techniques. Since the Magnetic Mallet was among the most innovative products evaluated this yew, it received a "CR First Look."
  • - Results: The Magnetic Mallet, as opposed to a hand mallet, improves patient comfort. There were no patient complaints either immediately after surgery or during any stage of recovery when using the Magnetic Mallet. The Magnet Mallet does seem to provide a better overall experience.
  • - Conclusions: Among the new technology evaluated this year, the Magnetic Mallet was among the most innovative and therefore worthy of a "CR First Look”. For dentists regularly accomplishing oral surgery and looking for cutting-edge technology, the Magnetic Mallet is a significant improvement over the conventional surgical, particularly for difficult extractions.

FLAPLESS LOCALISED MANAGEMENT OF SINUS FLOOR (LMSF) FOR TRANS-CRESTAL SINUS FLOOR AUGMENTATION AND SIMULTANEOUS IMPLANT PLACEMENT. A RETROSPECTIVE NON-RANDOMIZED STUDY: 5-YEAR OF FOLLOW-UP
  • - Background: Trans-crestal sinus lift procedures are well established.
  • - Purpose: to retrospectively analyse the efficacy of a flapless trans-crestal maxillary sinus floor elevation and simultaneous dental implant placement based on the Localised Management of Sinus Floor (LMSF) technique suitable for cases with sufficient width of keratinized tissue and of crestal bone but insufficient vertical dimensions of the bone below the sinus.
  • - Methods: 71 sinus elevations with simultaneous implant placement were performed on 52 consecutive patients. Following an initial pilot bur transmucosal perforation, the Magnetic Mallet was used with progressively larger osteotomes. The mallet osteotomes are initially directed palatally towards the cortex of the medial wall of the sinus and then redirected in a more vertical direction to create the final osteotomy for implant placement.
  • - Results: No significant complications were reported in the post-operative phase. The cumulative success rate during the observation period was 95%.
  • - Conclusions: Flapless Localised Management of Sinus Floor (LMSF) is a safe and effective surgical technique with minimal risks and with the advantage of low morbidity. Also, only native bone is used for augmentation and there is no need for additional grafting.

USEFULNESS OF MAGNETIC MALLET IN ORAL SURGERY AND IMPLANTOLOGY: A SYSTEMATIC REVIEW
  • Usefulness of Magnetic Mallet in Oral Surgery and Implantology: A Systematic Review
  • - Background: This systematic review aimed to answer the question: “Is the use of magnetic mallet effective in oral and implant surgery procedures in terms of tissue healing, surgery outcome, and complication rate compared to traditional instruments?”
  • - Methods: A literature search of PubMed, Scopus, and Web of Science databases (articles published until 1 October 2021) was conducted, in accordance with the PRISMA statement, using the keywords “magnetic mallet”, “electric mallet”, “oral surgery”, “implantology”, and “dental implant”.
  • - Results: Of 252 articles, 14 were included in the review (3 for teeth extraction, and 11 for implant dentistry). Out of a total of 619 dental extractions (256 patients) performed with the magnetic mallet (MM), no complications were reported. Implants inserted totaled 880 (525 patients): 640 in the MM groups (382), and 240 in control groups (133). The survival rate of implants was 98.9% in the MM groups, and 95.42% in the control groups.
  • - Conclusions: The use of MM may be helpful in oral and implant surgery procedures because of its safety, predictability, speed, and comfort of use.

A RETROSPECTIVE DIGITAL ANALYSIS OF CONTOUR CHANGING AFTER TOOTH EXTRACTION WITH OR WITHOUT USING LESS TRAUMATIC SURGICAL PROCEDURES
  • A Retrospective Digital Analysis of Contour Changing after Tooth Extraction with or without Using Less Traumatic Surgical Procedures
  • - Background: The present retrospective analysis aimed to compare two different single tooth extraction surgical approaches in both premolar and molar areas: less traumatic magneto-electrical versus conventional tooth extraction in minimizing the edentulous ridge volume loss. The study is therefore based on the comparison of the extractions performed with the Magnetic Dynamic technique of the Magnetic Mallet against extractions using traditional techniques.
  • - Methods: In the present retrospective control trial, 48 patients who underwent one-tooth extraction, were allocated either to control (28 sites treated with conventional tooth extraction procedures) or test group (20 subjects treated with less traumatic tooth extraction procedures by tooth sectioning and magnetoelectric roots subluxation). Intraoperatively, and then four months later, contours of the sockets were acquired through a laser intra-oral scanner. The digitally superimposed models were converted to dicom format first. Non-parametric tests were applied with a level of significance set at p < 0.01.
  • - Results: significant reductions of anatomical features were observed four months later in all the groups (p-values < 0.001) with volume losses leading to a final alveolar ridge volume of 0.87 ± 0.34 cm3 for atraumatic extractions and 0.66 ± 0.19 cm3 for conventional extractions.
  • - Conclusions: at four months, the less traumatic tooth extraction procedures by tooth sectioning and magnetoelectric root subluxation seemed to be able to better preserve the volume of the alveolar crest (reduction close to 22% with less traumatic extraction in molar sites) when compared to subjects treated with the conventional tooth extraction techniques. The research therefore shows how the extraction carried out with the Magnetic Dynamic technique generates a better preservation of the volume of the alveolar ridge and at the same time less loss of the external contour.

BIOMOLECULAR, HISTOLOGICAL, CLINICAL, AND RADIOLOGICAL ANALYSES OF DENTAL IMPLANT BONE SITES PREPARED USING MAGNETIC MALLET TECHNOLOGY: A PILOT STUDY IN ANIMALS
  • - Background: A new instrumentation exploiting magneto-dynamic technology (mallet) proposed for implant site preparation was investigated.
  • - Methods: In the tibias of three minipigs, two sites were prepared by mallet and two by drill technique. Primary stability (ISQ) was detected after implant positioning (T0) and at 14 days (T14). X-rays and computed tomography were performed. At T14, bone samples were utilized for histological and biomolecular analyses.
  • - Results: In mallet sites, histological evaluations evidenced a significant increase in the newly formed bone, osteoblast number, and a smaller quantity of fibrous tissue. These results agree with the significant BMP-4 augmentation and the positive trend in other osteogenic factors (biological and radiological investigations). Major, albeit IL-10-controlled, inflammation was present. For both techniques, at T14 a significant ISQ increase was evidenced, but no significant difference was observed at T0 and T14 between the mallet and drill techniques. In mallet sites, lateral bone condensation was observed on computed tomography.
  • - Conclusions: Using biological, histological, clinical, and radiological analyses, this study first shows that the mallet technique is effective for implant site preparation. Based on its ability to cause osseocondensation and improve newly formed bone, mallet technology should be chosen in all clinical cases of poor bone quality.

  • SURGICAL ADVANTAGES IN USING THE MAGNETIC MALLET
  • Bone expansion techniques, designed to increase peri-implant bone volumes using the native bone of the implant site and the use of bone expanders to stabilize implants in type 3 and 4 bone structures, are well documented techniques and recognized as valid and reliable by clinicians and literature. The critical point of these techniques is that the protocol involves the use of a surgical hammer to guide the instruments in creating the implant bone socket. The impact produced by the surgical hammer can cause patients to develop a dizzying syndrome that can also be very annoying and sometimes prolonged ...

THE UTILITY OF THE ELECTRIC MALLET
  • The Journal of Craniofacial Surgery, 2014; 25,793-795
  • THE UTILITY OF THE ELECTROMAGNETIC HAMMER
  • The Magnetic Mallet was used with a conservative and atraumatic procedure for the extraction of 427 teeth in 156 patients. The healings did not cause inflammation and the soft tissue closure by secondary intention was always completed in 2 weeks without bone exposure. Given the importance of the extraction procedure for the subsequent insertion of implants, in particular in the case of immediate post-extraction, the Mallet has proved to be a reliable and predictable tool.

MASTER'S DEGREE THESIS LM6, COURSE OF DENTISTRY AND DENTAL PROSTHESIS: LIFTING OF THE MAXILLARY SINUS WITH CRESTAL APPROACH USING THE MAGNETIC MALLET
  • Implant prosthetic solutions are increasingly widespread, even in those patients who, due to long-lasting edentulism, have vertical and / or horizontal bone deficits in the molar and premolar sectors of the upper jaw. In these patients, it is often necessary to increase the bone volume in these areas to allow for implant placement, by means of maxillary sinus floor elevation operations. Numerous authors have proposed techniques to lift the maxillary sinus floor, but to date the most used procedure for the small lift is the crestal approach using osteotomes, developed by Summers. This technique involves the use of osteotomes in combination with a manual surgical mallet to expand and then compact the bone in the area of interest, in order to offer adequate implant placement. Although this technique offers good results in terms of increasing bone volume and implant stability, it causes problems such as the onset of BPPV and technical difficulties encountered by the operator during the surgery. Through the use of the Magnetic Mallet these problems seem to be overcome. In fact, as emerges from the research reported in this thesis, the electric surgical hammer offers better control and precision of the osteotomy, plastic deformation of the bone tissue and avoids the onset of BPPV in patients undergoing maxillary sinus floor elevation operations.

MASTER'S DEGREE THESIS: EVALUATION OF CRESTAL BONE EXPANSION OBTAINED WITH A DYNAMIC MAGNETIC INSTRUMENT DURING IMPLANT PREPARATION
  • Implantology, despite being one of the oldest dental disciplines, has made enormous progress in the last half century.
  • In fact, this branch of dentistry today is one of the most widespread and used surgical practices for the partial or total rehabilitation of patients with edentulousness.
  • This methodology leads to reliable long-term results (1) and guarantees fixed rehabilitations for edentulous patients and not to compromise the natural teeth present. Implantology has thus become an integral treatment modality of prosthetic dentistry ...

BONE REMODELING AROUND IMPLANTS PLACED AFTER SOCKET PRESERVATION: A 10-YEAR RETROSPECTIVE RADIOLOGICAL STUDY
  • To evaluate and compare the long-term clinical and radiological outcomes of post-extraction sockets after ridge preservation either with porcine xenograft or collagen alone. Patients underwent single-tooth extraction in the posterior mandible. Fresh extraction sockets were filled with pre-hydrated cortico-cancellous porcine bone or collagen sponge. Two or 3 months later, a ridge expansion technique with immediate implant positioning placement was performed. Primary (alveolar width changes) and secondary outcomes (adverse events and longterm maintenance of buccal plate covering the implant) were evaluated.
