Abstract

Aim: To compare soft tissue dimensional changes and relative differences in soft and hard tissue volumes 4 months after single‐tooth extraction and three different treatment modalities: spontaneous healing (SH) and alveolar ridge preservation by means of a deproteinized bovine bone mineral and a collagen matrix, with (IMPL/DBBM/CM) or without (DBBM/CM) immediate implant placement. Materials and Methods: STL files from study casts obtained at baseline and after 4 months were matched to calculate buccal soft tissue linear and volumetric changes. DICOM files from CBCTs were superimposed to STL files allowing the evaluation of soft tissue thickness at baseline and 4 months. Results: Mean horizontal reduction accounted for 1.46 ± 0.20 (SH), 0.85 ± 0.38 (DBBM‐CM) and 0.84 ± 0.30 IMPL/DBBM‐CM, with no statistical differences. Soft tissue thickness had a significant mean increase of 0.95 for SH group, compared to a non‐significant mean decrease for DBBM‐CM (0.20) and IMPL/DBBM‐CM groups (0.07). Conclusion: A preservation technique with DBBM‐CM, with or without immediate implant placement, did not reduce the horizontal linear and volumetric changes at the buccal soft tissue profile significantly at 4 months after tooth extraction when compared to spontaneous healing. This is due to a significant increase in soft tissue thickness in spontaneously healing sites. [ABSTRACT FROM AUTHOR]
