Peri-implantitis – Surgical treatment with or without adjunctive graft material

shutterstock_70163050 dental implants

This review of the surgical treatment of peri-implantitis alone or in combination with adjunctive graft material included 5 small RCTs. The findings suggest improvements in marginal bone level (MBL) with graft material but the findings should be interpreted very cautiously because of the limited amount and quality of the evidence.

Early and delayed dental implant loading

shutterstock_12581266

This review of the outcomes of early and delayed loading of dental implants included 18 RCTs. The findings suggest that early and delayed loading protocols had similar clinical outcomes. However none of the included studies was at a low risk and 13 of the 18 studies were considered to be at high risk of bias. While the findings are similar to other reviews teh availabel evidence is of low to very low certainty.

This review of clinical outcomes for immediate and non-immediate (early or conventional) loading in single-implant restorations included 10 RCTs. All the included studies had follow up periods of 2 years or more although the number of implant failures was very low overall (11 out of 522) in both goups.

This review comparing the survival rate, marginal bone loss and clinical complications between extra-short implants (≤6 mm) and 6-mm-longer implants included 17 RCTs. While teh findings suggest no differences at 3 years the included studies are generally small and none of them were at low risk of bias.

This review comparing whether implant supported crowns on short or standard implants have similar clinical outcomes in the posterior alveolar bone included 5 RCTs. the findings suggested no differences at one year but that shorter implants performed less well at 5 years.

19 studies (6 RCTs, 13 prospective studies) were included in this review assessing whether the number of dental implants per jaw has an influence on implant and/or prosthesis survival rate and complications with the findings suggesting no influence.
