Statins as an adjunct to periodontal treatment?

This well conducted Cochrane review found no evidence that statins

This review of the adjunctive effect of statins on mechanical periodontal therapy included 15 studies 12 of which were RCTs. The findings suggest a positive effect on probing pocket depth, clinical attachment level, and intrabony defects but the overall quality of evidence is considered to be low.

Platform-switching dental implants improved bone preservation in short term

This review of platform-switching of dental implants included 17 RCTs and found that bone loss was lower than in regular platform implants, mean difference = -0.41mm (95%CI; -0.58 to -0.24) with no difference in failure rates RR = 1.10 (95%CI; 0.6–2.02).

Dental implants: platform switching may decrease bone loss

shutterstock_97814552

This review of platform switching for dental implants included 18 RCTs in a meta-analysis and suggests an improvement in marginal bone loss. However, the longest study were only of 3 years duration and the authors recommend the results be interpreted with caution due to the presence of uncontrolled confounding factors in the included studies.

Some evidence of reduction of peri-implant bone loss with platform switching

shutterstock_34428667

The concept and use of platform switching has gathered pace with the increasing numbers of dental implants being placed. platform switching (PS), where a small diameter implant abutment is placed in order to place the implant- abutment interface medial to the edge of the implant platform is considered to have a positive impact on maintaining [read the full story…]

Currently little evidence to support smoking as a risk factor for peri-implantitis

shutterstock_71105002

Dental Implants are now seen as a predictable treatment strategy for restoration in the partially or totally edentulous patient. Peri-implantitis is one potential complication and the prevalence has been reported as ranging from 6 – 28%. Smoking has been identified as a potential risk factor. The aim of this review was to assess the evidence [read the full story…]

Review suggests that smoking may have a harmful effect on peri-implant bone loss

shutterstock_29307445

It is believed that a number of factors may affect peri-implant bone resorption. These may include local factors (e.g. surgical procedures, implant design and restorative procedures), or patient related factors such as systematic disease, smoking status etc.   The aim of this review was to determine the influence of patient-related systemic risk factors (systemic disease, genetic [read the full story…]

Trial suggests no beneficial effect for platform switching for implants at 3 years

Cross section of a dental implant

Following placement of dental implants changes to bone level around the implant take place. Platform switching involves the use of an abutment with a smaller diameter than the diameter of the implant shoulder and is considered by some to lead to reduced peri-implant bone loss.   The aim of this trial was to assess the effect [read the full story…]

Lack of evidence to highlight differences in peri-implant bone loss between cement and screw retained prosthesis

Peri-implant bone loss is one parameter used to evaluate the success of dental implants.  The aim of this review was to compare peri-implant bone loss between cement and screw retained prosthesis. The Medline, SCOPUS, ISI Web of Knowledge and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched. Five journals were hand searched. Randomised [read the full story…]

Evidence of small benefit in peri-implant bone loss seen in first 5 years with platform switching

Cross section of a dental implant

This critical summary from the American Dental Association – Evidence-based Center (ADA-EBD) looks at a 2010 systematic review from Atieh et al. The aim of the review was to assess whether platform switching  (the placement of a smaller diameter prosthetic component on a larger diameter implant fixture) improved survival rate and bone loss.
