A connection structure using both a screw and friction is advantageous to secure an abutment to an implant. Understanding the biomechanics of the implant-abutment connection is necessary for the long-term clinical survival of a dental implant with decreased complications. The internal conical friction connection structure and micro-threads have shown favorable biological hard tissue response with exceptional structural features. The internal conical connection structure maintains the soft tissue seal and the marginal bone level around the implant. The durability of the implant wall thickness at the top is balanced via micro-threads with the load-transfer mechanism, resulting in proper peri-implant bone strain. These two structural devices are designed to achieve implant-abutment connection stability by redistributing an external load and by minimizing screw loosening events that cause implant component fractures and marginal bone loss.

Abstract Background This retrospective study investigates the change in the peri-implant bone level (PBL) during the 2nd decade of intraoral function in patients complying with a ‘supportive implant therapy’ (SIT) program. The results were statistically analyzed with respect to the implant abutment connection used. Methods In a private practice, only patients with 20-year SIT compliance were identified. Of these, all patients with 10- and 20-year radiographs available were selected. Therefore, no control group was possible and implant losses had to be excluded. Two experienced researchers assessed the peri-implant bone levels. As three different abutment connection concepts (bone-level butt-joint, bone-level conical and tissue-level conical) and two different implant surfaces (machined vs. roughened) were involved, statistical analyses were performed to detect potential differences. Results Ninety-three implants from 36 patients with 20-year SIT compliance and available radiographs were included in the study. At study baseline (10 years intraoral), a mean bone loss of − 1.7 mm (median − 1.2; standard deviation [sd] 1.4, range: 0 to − 7.2) was recorded. After 20 years, we found a mean bone loss of − 2.5 mm (median − 2.3, sd 1.79, range: − 0.5 to + 7.4). Furthermore, we found a mean bone loss of 0.8 mm in intraoral function from year 10 to year 20 (mean: 0.08 mm per year); this change was independent of the abutment connection type. Conclusions During the 2nd decade of function, peri-implant bone loss in patients with SIT compliance might be small in value and should not be expected in all implants.
