Immediate placement can be complicated by the presence of bony deficiencies in the buccal alveolar bone. These deficiencies, which can originate through inflammation or trauma, can have a negative effect on the final aesthetic outcomes. The purpose of this study, presented at the 2018 EAO Congress, was to compare aesthetic outcomes of immediate single-tooth implants with and without bony deficiencies.
The study included 24 patients with a mean age of 54 years. Single implants were placed immediately following extraction in the maxillary incisor or canine region. Half of the implants were placed next to bone defects, with the other half placed in intact sockets. All implants received zirconia abutments.
To assess the aesthetic outcomes, Pink Esthetic Scores (PES) were taken one year following placement. No significant difference was observed between the two patient groups, but a higher rate of alveolar deficiencies and soft tissue discolouration was noted in the defect group. Mucosal recession and marginal bone loss were similar between the two groups. Overall, the authors conclude that although there were no major differences observed, aesthetic outcomes may be less predictable in cases involving bony deficiencies.
