Efficiency and Risk Assessment of Dental Bridge Removal Tools on Implant Abutments
Journal of Functional Biomaterials 2026, 17, 33 · DOI 10.3390/jfb17010033 · CC BY 4.0 · OSSEOTOUCH summary
In-vitro study of 210 retrieval tests (7 bridge geometries × 2 luting agents × 3 tools × 5 replicates), comparing the Magnetic Mallet, sliding hammer, and Coronaflex. With temporary cement, the Magnetic Mallet showed efficiency comparable to the sliding hammer while generating lower forces; Coronaflex had lower success rates and higher forces. With permanent cement, most bridges were not retrievable, and the sliding hammer occasionally damaged abutment screws. The study was in vitro and retrievals were performed by one operator, so it does not establish in-vivo clinical outcomes.

Uncontrolled case series of 29 teeth extracted in 9 patients. At 3 months, mean buccolingual bone resorption was 1.54 mm, comparable with published data; mean extraction time was 3.5 minutes, with no difference between the two operators. The small sample and short follow-up do not establish superiority over conventional techniques.

Conference abstract on 35 implants planned in the maxillae of 15 patients and prepared with guided magnetodynamic surgery. One implant in the tuber did not initially osseointegrate; after removal and a 3-month wait, the replacement implant integrated. The authors report a 97% rate (34/35). In the subgroup assessed with CBCT and superimposition, accuracy was high with negligible discrepancies, but no subgroup size or quantitative values were published. As a brief abstract without a control group, it provides no extended follow-up or complete data from which to generalize efficacy or accuracy.

Ex vivo study in low-density porcine ribs using two implant macro-designs (Five and TiSmart) and four groups of 34 implants. In the planned comparisons, magnetodynamic preparation produced favorable peak insertion torque, ISQ, and peak removal torque values versus drill preparation. This in-vitro model evaluates primary stability, not clinical outcomes or osseointegration.

In-vitro study on dry porcine ribs comparing Magnetic Mallet and conventional drills for site-diameter accuracy, specimen weight loss, and temperature change. Under the experimental conditions, the mallet showed greater accuracy, less material loss, and a smaller temperature change. Surface roughness and osseointegration were not measured, and the study provides no clinical outcomes.

Single case report of a 69-year-old woman with post-traumatic edentulism, rehabilitated in the maxilla with six narrow implants, guided surgery, a magnetodynamic instrument, and immediate loading. Definitive rehabilitation was completed at 6 months with a favorable outcome in this case. A single case is not generalizable; larger studies and long-term follow-up are required.

Split-mouth pilot study of 22 patients, each with three non-adjacent teeth randomized to conventional instruments, Magnetic Mallet, or piezosurgery. There were no statistically significant differences in postoperative pain or wound healing; extraction time was significantly shorter with Magnetic Mallet. Further randomized controlled studies are required.

This study followed 36 patients who received 93 immediately loaded implants after split-crest ridge expansion. At 2 years, implant survival was 98.92%, with mean crestal bone loss of 1.02 ± 0.48 mm. The study specifically evaluates immediate loading after split crest.

Prospective randomized study of 46 patients: 23 split-crest procedures used a hand mallet and 23 used an electrical mallet, with 181 implants placed immediately. Survival at 24 months was 98.31%. Ridge-width changes did not differ significantly between groups; the authors report clinical advantages of the magnetic mallet during the procedure.

Five-year retrospective study of 38 patients treated with split crest and immediate implant placement. In the comparative analysis of 16 maxillae and 16 mandibles, mean width and volume gains were greater in the maxilla; survival was 95.5% in the maxilla and 100% in the mandible, with one maxillary failure. The authors state that survival conclusions are premature without statistical support.

Retrospective study of 18 implants using lateral and apical displacement of the palatal wall through a transcrestal approach. At 1 year, bone volume had increased significantly and ridge width had increased from 5.1 to 6.5 mm; marginal bone loss was 1.0 ± 0.8 mm. The study did not directly compare this technique with the traditional lateral approach.

Retrospective study of 40 patients with an initial bone height of 2.9 ± 0.6 mm. The two-stage technique produced mean gains of 3.1 ± 0.6 mm after the first surgery and 4.4 ± 0.6 mm after the second, with an overall height of 10.3 ± 0.6 mm at 3 years. No implant failures were recorded in the selected sample.

Retrospective controlled analysis of 48 patients: 28 conventional extractions and 20 less-traumatic procedures using tooth sectioning and magnetoelectric root subluxation. At 4 months, both groups showed volume reduction; at molar sites, loss was lower with the less-traumatic procedure (22.3% versus 44.3%). The actual follow-up is 4 months, not 12.

Prospective study of 36 patients and 50 implants in posterior maxillary regions with type 3 or 4 bone, comparing osteotomes driven by magnetic and hand mallets. Overall survival at 24 months was 96%; marginal bone levels were stable and did not differ significantly between groups. This study concerns maxillary bone condensing, not 3-year mandibular ridge expansion.

Prospective study of 32 patients and 70 implants placed immediately in fresh extraction sockets with simultaneous sinus-floor elevation. Cumulative survival at 2 years was 98.57%, and mean bone gain was stable at 4.08 ± 1.25 mm. No membrane perforation, vertigo, distress, nausea, or vomiting was reported in the study sample.

Pilot study in three minipigs, with tibial sites prepared by mallet or drill and evaluated at placement and 14 days. The authors observed more newly formed bone and osteoblasts and less fibrous tissue at mallet sites; ISQ increased in both groups without a significant between-technique difference. These are short-term preclinical findings from a small animal sample.
