Title Transmucosal Dental Implant Placement with Bone Augmentation Shows No Difference in Bone Levels or Soft Tissue Indices from Submerged Dental Implant Placement with Bone Augmentation
Clinical Question In patients receiving dental implant placement with lateral bone augmentation, does a transmucosal dental implant show a significant difference in bone levels and soft tissue indicators in comparison to a submerged dental implant?
Clinical Bottom Line In patients receiving dental implants in conjunction with lateral bone augmentation, submerged dental implant placement may offer no benefit over non-submerged placement as measured by bone level and soft tissue indicators.

#1) 22697581Cordaro/201352 dental implants with bone augmentation: 27 submerged, 25 non-submergedRandomized Controlled Trial
Key resultsThe study shows no significant difference between the two groups after 2 years of follow-up. Bone resorption was found in both groups (0.37 ± 0.49 mm in the submerged group and 0.54 ± 0.76 in the non-submerged group; P < 0.001). Probing depths (2.5 vs. 2.4 mm), bleeding on probing (BOP-positive sites: 8.8% vs. 11.5%) and clinical attachment loss (2.8 vs. 2.4 mm) were not significantly different between the submerged and the non-submerged groups, respectively.

Comments on
The Evidence
Validity: This article directly compared the two groups as part of a secondary analysis of an ongoing larger clinical trial. The study was conducted in 12 centers, and the sample was randomly distributed between submerged and non-submerged placement. The study used a retrospective assessment of patients completing 2 years of evaluation of the implant in aesthetic (anterior) area, limiting definitive conclusions that can be be drawn from this comparative report. Perspective: It is commonly thought that submerged dental implant placement is preferred if lateral bone augmentation is required in conjunction with implant placement. Based on this retrospective comparative study, both options (submerged and non-submerged) appear to have similar clinical outcomes.
Applicability This information offers the dentist some guidance as to whether or not to submerge dental implants placed in an aesthetic (anterior) area in conjunction with lateral bone augmentation.
