Clinical and patient-reported outcome of implant restorations with internal conical connection in daily dental practices: prospective observational multicenter trial with up to 7-year follow-up

Abstract

Background: The interpretation of the results of randomized clinical trials is often questioned in relation with daily circumstances in practices. This prospective observational multicenter study was instigated to reflect the need for information in real-life situations with dental implants with internal conical implant-abutment connection (Conelog implant system). The implants were followed up at least 5-year post-loading; survival analysis (Kaplan-Meier), changes of soft tissue, and bone level over time, as well as patient satisfaction were evaluated. Results: In total, 130 dental implants were placed in 94 patients (64 female, 30 male). Mean age of patients was 50.4 ± 13.7. At 5-year post-loading, 104 implants in 76 patients were available for evaluation. The cumulative implant survival rate was 96.6%. After an initial bone remodeling process post-surgery (bone loss of − 0.52 ± 0.55 mm), the bone level change remained clinically stable from loading to 5-year post-loading (− 0.09 ± 0.43 mm). Patient satisfaction surveyed by questionnaire (comfort, ability to chew and taste, esthetics, general satisfaction) steadily increased towards the end. At the last study follow-up, all the patients rated their general satisfaction as either very satisfied (87.5%) or satisfied (12.5%). Conclusion: The study implants have shown to be highly effective with reliable peri-implant tissue stability over the 5 to 7 years of observation for both single tooth restorations and fixed partial dentures while used in standard conditions in daily dental practice. The results obtained are comparable with those obtained in controlled clinical trials.

Clinical and radiographic performance of late placed and early loaded dental implants with a conditioned hydrophilic surface in posterior mandible sites: A prospective case series with an 8.5‐ to 9.5‐year follow‐up

“…Similar studies also reported high patient satisfaction with implant restorations in partially dentated arches. [40][41][42] Considering the strengths and limitations of this study, despite its relatively small sample, the reported long-term data can provide valuable information regarding the use of dental implants with intraoperatively conditioned hydrophilic surfaces in an early loading scenario.…”

Assessment of salivary alpha amylase and mucin-4 before and after non-surgical treatment of peri-implant mucositis

“…In the present study, all implants were in function for a mean duration of approximately 3 years, which is a relatively short duration. Studies [2,44,45] have shown that under physiologic conditions dental implants demonstrate minimal CBL up to 7 years of PL. The authors applaud results reported in a non-interventional multicenter study [45] according to which, dental implants placed in individuals (mean age approximately 50 years) demonstrate CBL of 0.52 ± 0.55 mm after 36 months of PL.…”

Effect of Different Dental Implant Prosthetic Joints on Marginal Bone Loss: Emerging Findings from a Bayesian Network Meta-Analysis (NMA) and Systematic Review

“…A total of eight different prosthetic joint connections have been considered: internal hexagonal joint 1 mm below the bone level position [19][20][21][22][23][24][25][26][27], internal hexagonal joint at bone level position [19], external hexagonal joint at bone level position [23,25,26,[28][29][30][31], Internal conical prosthetic joint with index [19,22,27,28,[31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46], cone morse 1 mm below the bone level position [23][24][25][26]30,[47][48][49], cone morse at the bone level position [49], 1). A total of eight different prosthetic joint connections have been considered: interna...…”
