“…Therefore, vertical bone in the present study was close from expected bone loss at first year and even in the years after. 3,11,15,26,28 However, more bone loss was expected after the first year especially in this smokers' cohort and at 5 years of overdenture service. The present results could be claimed to the frequent maintenance and follow-up which was essential to keep bone loss within the acceptable limit.…”

“…Second, many articles explained the hazards of smoking on the peri-implant tissues and their integration but there are many other confounding factors in the clinical conditions that may contribute to the treatment's outcome. [6][7][8][9][10][11]15 Few studies separated successfully the effect of these confounding factors. 7,10 Finally, the difference between the treatment options applied by our study and other studies may play a role in the final results.…”

“…6,11,12 The mean values of bone loss and implant survival rate were monitored in several researches as reliable parameters for implant success in patients with smoking habit. [11][12][13][14][15] Accordingly, Peñarrocha et al, 11 monitored peri-implant marginal bone loss in a patient's cohort and confirmed their relations to smoking habit, implant position, and morphology. Furthermore, a systemic review and meta-analysis, concluded that smoking had a negative effect on peri-implant tissue integrity and could be listed as a factor initiating peri-implantitis.…”

“…Mini implant overdenture is a successful treatment and could be considered as a standard health care for completely edentulous patients. 5,15,18 Accordingly, this study was conducted to evaluate the use of the mini implant mandibular overdenture, as a definitive, stable line of treatment capable to enhance oral health quality of life, in a cohort of smokers within 5 years of function. No study was conducted to reveal the value of using mini implants to retain complete dentures of smokers.…”

Objectives Studies considered edentulous patients having smoking habit as a compromised oral condition. This research examined the value of using mini implant mandibular overdenture to maintain long-term satisfactory levels of oral health quality of life and marginal vertical bone loss. Materials and Methods Twenty-nine edentulous patients with smoking habit received four mini implants in the mandible loaded by overdentures. The present study monitored patients radiographically for vertical bone loss after (1 month, 1, 3, and 5 years) of treatment. Patients were also evaluated by oral health impact profile 14 (OHIP-14) pretreatment and at 1 and 5 years of treatment. Statistical Analysis Repeated measure analysis of variance with Bonferroni’s test as a post-hoc test was used to see the difference among time points. Independent sample t-tests were used to compare between anterior and posterior mini implant positions after 5 years of follow-up. OHIP-14 questionnaire was analyzed by Wilcoxon signed ranks for pairwise comparisons at different evaluation times. A Holm-Bonferroni correction method was used to control the familywise error rate. Results The mean of the bone height changes showed a significant difference between 1-month data and all other evaluation intervals while no significance was calculated among other evaluation intervals. Bone loss of the mini implants placed anteriorly was less than those placed posteriorly with a statistically significant difference. A significant reduction in the OHIP-14 score levels was observed between pretreatment and both 1 and 5 years of treatment. No significance was seen between the first and fifth year after treatment. Conclusion Mini implant overdenture could maintain satisfactory marginal bone level changes and oral health quality of life for patients with smoking habit after 5-year follow-up period.

“…Another factor influencing peri-implant bone loss and dental implant survival is smoking [12,42,[72][73][74][75][76]. According to various studies, smoking has a negative effect on osseointegration [77][78][79][80][81][82][83] and its dose-related impact [84].…”

vascular disease) affecting therapyial preliminary considerations of dental implant treatment. However, in case of HIV-positive patients, the dental implant failure rate would not increase due to affective factors (e.g., prophylactic antibiotic treatment, the administration of active antiretroviral therapy, and control of the CD 4+ T lymphocyte counts). Therefore, these patients have no clinical signs of mobility or infection in this treatment and much more attention should be paid to these patients and they should be treated with controlled oral surgical procedures.

Objective Bone augmentation delays implant placement and increases risks due to additional surgeries. Implant systems compatible with reduced alveolar bone volume are required. To design, manufacture, and test a non‐cylindrical dental implant system using piezotomes and custom‐designed matching titanium mini‐implants to address the needs of patients with missing teeth and narrow jawbone. Materials and methods Tapered mini‐implants with a rectangular cross‐section (4.6 mm × 2.1 mm) were machined with dimensions that could accommodate narrow alveolar ridges. The performance of the implants were tested in both static and fatigue cycle 30° compression tests. Tapered, rectangular cutting tools that matched the overall trapezoidal morphology of the implant were also designed. These novel tools were engineered to be compatible with commercially available piezoelectric osteotomes. Tools were optimized using finite element analysis and were manufactured accordingly and were used by a periodontal surgery team in a pork rib bone model to monitor utility of the device and ease of use. Results The rectangular design of the implant allows for a full occlusal load due to the larger implant flexural rigidity compared to a similar diameter mini‐implant with a standard cylindrical design. During 30° compression fatigue tests, the implant tested at 340 N did not fail after 5M cycles as shown in Kaplan‐Meier survival curves. Finite element analysis allowed for functional optimization of the roughing and finishing tools. In the pork rib model, these tools successfully cut trapezoidal holes that matched the dimensions of the implant. Conclusions The implant system here demonstrates the feasibility of a mini‐implant system that has superior flexural rigidity and potentially circumvents the need for patient bone augmentation.
