Alveolar ridge changes 1‐year after early implant placement, with or without alveolar ridge preservation at single‐implant sites in the aesthetic region: A secondary analysis of radiographic and profilometric outcomes from a randomized controlled trial

Objectives To assess both the radiographic and profilometric outcomes of early implant placement with or without alveolar ridge preservation (ARP) (using two different ARP techniques) after 1 year of loading. Materials and Methods Seventy‐five patients with a failing single tooth in the anterior max...

Description
Summary:Objectives To assess both the radiographic and profilometric outcomes of early implant placement with or without alveolar ridge preservation (ARP) (using two different ARP techniques) after 1 year of loading. Materials and Methods Seventy‐five patients with a failing single tooth in the anterior maxilla were randomly allocated to three groups (1:1:1): (a) ARP using demineralized bovine bone mineral containing 10% collagen (DBBM‐C) covered by a collagen matrix (CM), (b) ARP using DBBM‐C covered with a palatal graft (PG), and (c) unassisted socket healing (control). Eight weeks after tooth extraction, early implant placement was performed in all patients. Cone‐beam computed tomography (CBCT) and impressions were taken 8 weeks after tooth extraction (ARP/unassisted healing) prior to implant placement and 1‐year post‐loading. Radiographic and profilometric outcomes were evaluated. Results Out of the 70 patients available for re‐examination at 1‐year post‐loading, 55 datasets could be assessed (ARP‐CM 19; ARP‐PG 17; Control 19). The need for additional guided bone regeneration (GBR) at implant placement amounted to 31.6% (ARP‐CM), 29.4% (ARP‐PG), and 68.4% (unassisted healing). Adjusted models revealed that residual buccal bone height and additional GBR at implant placement significantly influenced the magnitude of the alveolar changes at 1 year (p
