Influence of Z Shaped Incisions on Healing and Interproximal Bone Loss in Comparison With Conventional Sulcular Incisions in Implant Surgery

Implant stability plays a critical role for osseointegration, without osseointegration long term success cannot be achieved, primary stability occurs from mechanical attachment with the cortical bone. It is the gold standard for success of implants. This is a descriptive clinical study carried out in saveetha dental college and hospital, Poonamallee, Chennai. All the patients who underwent single or two-unit implant surgery were selected. The study setting was done from university predominantly south Indian populations and data with regard to primary stability at placement, level of the implant with bone, crestal bone loss at stage 2 recovery were retrieved from the digital case sheets. Data were entered using SPSS software, and Chi-square test was used for inferential analysis, with a P-value < 0.05 was said to be statistically significant. The results obtained indicate more implants are placed with primary stability in 30-40 Ncm(49.8%). More frequently placed crestal relation is equi crestal region (84.4%) and crestal bone loss was less than 1-2mm is seen(87.3%) at stage 2 recovery. The results were subjected to statistical chi-square test, and it is observed that primary stability at 30-40 Ncm or greater did not have any significant association with crestal bone loss. An equi crestal placement of the implant was preferred irrespective of implant type.

The aim of this study is to compare the implant placement deviations and evaluate the 1-year post-implant placement bone loss of pilot and fully guided implant placement protocols. In the first method, the pilot drill is used for guide surgery, and the following procedure is a method for performing implant surgery in a non-guided protocol. The second method is to perform fully guided surgery. A total of 74 implants in 20 patients were included. Postoperative CT scans were used to compare the implant placement deviations with the preoperative plan. In addition, bone loss was compared one year after surgery. In shoulder area, the implant deviations from the planned positions for dx(mesio-distal), dy(bucco-lingual), dz(vertical) dimensions, mean deviations with pilot-guided protocol (n = 31) were 0.50 ± 0.42 mm, 0.61 ± 0.55 mm, 0.87 ± 0.71 mm, and 1.33 ± 0.75 mm, respectively. The corresponding deviations for fully guided protocol (n = 41) were 0.50 ± 0.52 mm, 0.29 ± 0.27 mm, 0.56 ± 0.51 mm, and 0.96 ± 0.57 mm. In apical area, the corresponding deviations for pilot-guided protocol were 0.75 ± 0.72 mm, 0.61 ± 0.46 mm, 0.98 ± 0.76 mm, and 1.54 ± 0.87 mm. Deviations for fully guided protocol were 0.91 ± 0.90 mm, 0.44 ± 0.39 mm, 0.54 ± 0.51 mm, and 1.38 ± 0.76 mm, respectively. Angular deviations were 3.33 ± 3.23° with pilot-guided protocol and 3.90 ± 1.85° with fully guided protocol. The average bone loss after 1 year was 0.50 + 0.29 mm and 0.50 ± 0.24 mm, respectively. In the shoulder area, dy(bucco-lingual) of horizontal deviations, vertical deviations, and mean value of the deviations showed a statistically significant difference between fully guided and pilot-guided (p = 0.005, p = 0.033, and p = 0.023, respectively). In the apical area, vertical deviations showed a statistically significant difference. However, the mean value of the deviations did not show a statistically significant difference (p = 0.347). There was no statistically significant difference in angular deviations (p = 0.59).

Background: the prognosis of peri-implant surgery can be affected by poor decontamination of the implant surface, which could be improved with the use of titanium brushes. The objectives of this systematic review were to evaluate the effectiveness of titanium brushes in the decontamination of the implant surface in terms of plaque index, probing depth, bleeding on probing and bone loss/gain; as well as its effectiveness according to the type of peri-implant bone defect. Methods: an electronic search was carried out in the PubMed, Scopus, Cochrane and Embase databases, as well as a manual search. The search strategy included four keywords: “Peri-implantitis”, “Periimplantitis”, “Implant Surface Decontamination” and “Titanium Brush”. Randomized controlled studies published in the last 10 years were included and systematic reviews, in vitro studies and animal studies were excluded. Results: 142 references were found, from which only four articles met the inclusion criteria. All of the studies included in the present review reported beneficial results in terms of probing depth, gingival index and radiographic bone loss and gain after implant surface decontamination adjuvated by titanium brushes. Conclusions: titanium rotary brushes show improvements in the evolution and prognosis of peri-implant surgery, although more long-term studies are needed to draw more solid conclusions.
