“…And in the present study smoking was identified as the other predictor to exert some statistically significant effect on the failures up to abutment connection. A recent meta-analysis analyzing more than 100 studies has shown that failures of implants inserted in smokers are 2.23 times more likely to happen than failures of implants inserted in nonsmokers (Chrcanovic et al, 2015). The increase of implant failure rates due to smoking is hypothesized to be related mainly to the effect of smoking in osteogenesis and angiogenesis (Ma et al, 2010).…”

Abstract:The purpose of the present study was to assess the influence of local and systemic factors on the occurrence of dental implant failures up to the 2nd stage surgery (abutment connection). This retrospective study is based on 2,670 patients who received 10,096 implants and were consecutively treated with implant-supported prostheses between 1980 and 2014 at one specialist clinic. Several anatomical-, patient-, health-, and implant-related factors were collected. Descriptive statistics were used to describe the patients and implants. Univariate and multivariate logistic regression models were used at the patient-level as well as at the implant-level, to evaluate the effect of explanatory variables on the failure of implants up to abutment connection. A generalized estimating equation method was used for the implant-level analysis, to account for the fact that repeated observations (several implants) were available for a single patient. Overall, 642 implants (6.36%) failed, of which 176 implants (1.74%) in 139 patients were lost up to the 2nd stage surgery. The distribution of implants in sites of different bone quantities/qualities was quite similar between implants lost up to and after abutment connection. Smoking and the intake of antidepressants were the statistically significant predictors in the multivariate model.

Nevertheless, failures still happen despite the high implant survival and success rates (Chrcanovic et al., 2014). Failures of dental implants can be subdivided into early and late failures, depending on whether they occur before or at abutment connection surgery (early) or after occlusal loading by a prosthetic restoration (late). This subdivision is relevant as it is suggested that the failures in these two distinct time periods may be associated with different factors. An early failure of an implant results from an inability to establish an intimate bone-to-implant contact. In this case the bone healing after implant insertion is impaired and may be influenced by local and systemic factors (Alsaadi et al., 2007). Systemic diseases and compromising risky habits may affect oral tissues by increasing their susceptibility to other diseases or by interfering with wound healing. Surgical conditions, submission to radiotherapy, and the intake of medications by the patient may play a role on the outcome of implants. When it comes to late implant failures, the oral microbial environment, parafunctional habits, and the prosthetic rehabilitation variables are also taken into account. Although many studies have shown the influence of local and systemic factors in the long-te...

“…However, the literature suggests that smoker patients must be informed of a higher risk of implant failure. According to a recent meta-analysis [24], smoking consumption statistically affects implant success rate (p < 0.00001) with an odds ratio of 2.23 (CI 95% [1.96; 2.53]) compared to nonsmoker patients. Tobacco increases the incidence of postoperative infections as well as peri-implant bone loss.…”

--Introduction:In recent years, the immediate loading procedure for the rehabilitation of edentulous jaws has gained popularity among patients and practitioners. The purpose of this study was to evaluate implant and prosthetic success rates for the rehabilitation of edentulous maxillae using tilted distal implants and immediate loading of prostheses, after 2 years. Material and method: Patients included in the study received a complete prosthesis of the upper arch, attached to 4, 5 or 6 implants. The provisional prosthesis was fixed the same day the implants were placed. After a period of osseointegration, the provisional prosthesis was replaced by a definitive prosthesis with a titanium framework made using computer-aided design/computer-assisted manufacturing (CAD/ CAM) technology. Judgment criteria were the implant success rate, the provisional prosthesis success rate, and the definitive prosthetic success rate. Results: Two hundred and forty-two implants were placed in 48 patients. Five implants were lost, resulting in an implant survival at 2 years of 97.9%. Two provisional fixed prosthesis had to be temporarily replaced by a removable solution, resulting in a provisional prosthesis success rate of 95.8%. The definitive prosthesis success rate was 100%. Discussion: Use of a provisional prosthesis during the osseointegration period is essential, both for the preparation of the final prosthesis as well as for proper management of potential implant failures. Implant failures are more easily managed if at least five implants were originally placed.

“…[14] The smoking habit was considered as exclusion factor because the smoking significantly affects the implant failure rates, the incidence of postoperative infections, as well as the marginal bone loss as revealed by a recent systematic review. [15] An added failure rate of about 8% was noticed in smokers that occurred either at the implant exposure or after a short time of implant loading. [16] In this study, the effect of conventional versus Schlosser's techniques during competes denture construction was compared to evaluate the effect of these different approachs on the implant stability and marginal bone loss.…”

Background:The conventional method of complete denture fabrication has many problems that include lack of uniform distribution of occlusal forces to the basal seat, causing inflammation, ulcers in the supporting tissues, more rapid residual ridge resorption, increase patient discomfort, increase parafunctional movements, and the need for frequent adjustments. Aim: The aim of this study is to evaluate and compare the effect of two different fabrication techniques for complete over dentures supported by mandibular implants. Methodology: A total of 24 edentulous subjects were eligible for inclusion. Using a random sampling system, conventional or Schlosser's technique was used to fabricate the dentures. Two implants were placed in the canine area of all patients. After 3 months, ball attachments were connected to the implants, and the denture delivered with the retentive components incorporated in the denture base. At the follow-up examinations, implant stability and marginal bone loss were evaluated at 3, 6, and 12 months. Results: The sample of 24 patients, with a mean age of 55.2 years, was included in this study. All patients attended the 12-month follow-up. The complete denture fabricated by Schlosser's technique showed significant more implant stability and less bone loss when compared to conventionally fabricated dentures. Conclusion: The Schlosser's technique is considered as predictable methods of complete denture construction. Consequently, this technique has a positive effect on the implants that supported mandibular overdenture. The more harmonious occlusion result from this technique results in better implant stability and decreases the rate of bone loss around the implants. Clinical Significance: The denture fabricated with Schlosser's technique results in more harmonious occlusion that suggested as one requirement of successful dental implants.
