“…However, rough implant surfaces are associated with many risks, including complications, peri-implant infections, and increased marginal resorption, as evidenced by previous literature data. For the posterior maxilla, bone augmentation can be replaced by sinus membrane lift during simultaneous implant placement without bone grafts [ 10 ]. This clinical study aimed to clinically and radiographically assess the healing of endosseous implants having different surface characteristics in nongrafted and grafted bone.…”

BackgroundTotal treatment time in implant placement can be significantly reduced by placing immediate implants into the freshly extracted sockets. Also, immediate implant placement can act as a guide for proper and accurate implant placement. Additionally, in immediate implant placement, the resorption of bone associated with the healing of the extraction socket is also reduced. This clinical study aimed to clinically and radiographically assess the healing of endosseous implants having different surface characteristics in nongrafted and grafted bone. MethodologyIn 68 subjects, 198 implants were placed, including 102 oxidized (TiUnite, Göteborg, Sweden) and 96 turned surface implants (Nobel Biocare Mark III, Göteborg) were placed. Survival was considered with clinical stability and acceptable function with no discomfort and no radiographic or clinical signs of pathology/infection. Rest cases that showed no healing and implant no osseointegration were considered failures. Clinical and radiographic examination was done by two experts after two years of loading based on bleeding on probing (BOP) mesially and distally, radiographic marginal bone levels, and probing depth (mesial and distal). ResultsFive implants failed in total where four implants were with the turned surface (Nobel Biocare Mark III) and one was from the oxidized surface (TiUnite). The one oxidized implant was in a 62-year-old female and was placed in the region of mandibular premolar (44) of length 13 mm and was lost within five months of placement before functional loading. Mean probing depth had a nonsignificant difference between oxidized and turned surfaces with the mean values of 1.6 ± 1.2 and 1.5 ± 1.0 mm, respectively, with P = 0.5984; mean BOP in oxidized and turned surfaces was 0.3 ± 0.7 and 0.4 ± 0.6, respectively (P = 0.3727). Marginal bone levels, respectively, were 2.0 ± 0.8 and 1.8 ± 0.7 mm (P = 0.1231). In marginal bone levels related to implant loading, a nonsignificant difference was seen in early loading and one-stage loading with P-values of 0.06 and 0.09, respectively. However, in two-stage placement, significantly higher values were seen for oxidized surfaces (2.4 ± 0.8 mm) compared to turned surfaces (1.9 ± 0.8 mm), with P = 0.0004. ConclusionsThis study concludes that nonsignificantly higher survival rates are associated with oxidized surfaces compared to turned surfaces after two years of follow-up. Higher marginal bone levels were seen in oxidized surfaces for single implants and implants placed in two stages.

“…Previous studies have generally demonstrated that smokers have less favorable healing in response to both non-surgical and surgical periodontal therapy [ 38 , 39 , 40 , 41 , 42 ] and they may also respond differently to peri-implant disease therapy. In fact, the negative effects of smoking on wound healing are mainly caused by chemical substances as nicotine, carbon monoxide, hydrocyanic acid, and nitrogen oxide [ 43 ], but the exact mechanisms by which tobacco exerts its influence on healing and more generally on the health of periodontal tissues are not completely elucidated and could be influenced by multiple factors [ 44 , 45 ].…”

Impact of Smoking Habit on Peri-Implant Indicators following Different Therapies: A Systematic Review

Peri-implant disease and its treatment is becoming a major concern for clinicians as the number of implants placed each year is rising. Smoking is a common habit, and it is associated with an increased risk of developing peri-implant disease. The role of smoking in the response to peri-implant treatment has never been investigated. Searches were conducted in electronic databases to screen articles published until August 2021. The included studies had at least two groups of patients: peri-implant disease only or peri-implant disease and smoking status. Outcomes of interest included plaque index (PI), probing depth (PD), bleeding on probing (BoP), radiographic crestal bone loss (CBL), and analysis of peri-implant sulcular fluid. Seven hundred and forty-nine articles were found in the databases, only 71 articles potentially qualified. A total of seven studies with a minimum follow-up of six months were included. There is no homogeneity in the diagnosis, smoker definition and treatment proposed. All surgical and non-surgical treatment have statistically significantly different outcomes in smokers and nonsmokers. Recognizing this study’s limitations, we conclude that smoking might play a significant role on the outcome of peri-implant disease treatment. None of the proposed treatments appear to be significantly more effective.

Background: Despite various complications and failure factors, newer implants are designed that allow placement in sub-optimal conditions to allow the operator to place implants at sites with low bone quality. These newer designs also allow improved stability with higher survival rates in the short term. Aims: The present study was undertaken to evaluate long-term efficacy and risk factors associated with dental implant placement for full mouth rehabilitation. Materials and Methods: In 24 subjects, 438 implants were placed. The data collected were surgical and were retrospectively analyzed. The data collected included medical history, local, patient satisfaction, marginal bone loss, and systemic risk factors affecting implant survival. Outcome variables assessed were peri-implantitis, implant success, and survival at the follow-up visit. The data were expressed in terms of percentage and number, and the results were derived. Results: Peri-implantitis was seen in 31.05% ( n = 136) of implants. 76.02% ( n = 333) of implants were considered successful at recall. Concerning survival, compromised and satisfactory survival was shown by 10.04% ( n = 44) and 2.96% ( n = 13) of implants, respectively. 10.95% ( n = 48) of implants were considered as failures. Conclusion: The present study concludes that good, long-term survival rates are associated with full mouth rehabilitation using dental implants.
