Purpose This study evaluated changes in the horizontal and vertical dimensions of the buccal alveolar bone and soft tissue over a 1‐year period following implant prosthesis. Materials and Methods Thirty‐three participants with no history of guided bone regeneration or soft tissue augmentation underwent dental implant placement with different types of connections. The dimensions of the buccal alveolar bone and soft tissue were evaluated immediately and at 1 year after prosthesis from reconstructions of cross‐sectional cone‐beam computed tomography images. Results The vertical and horizontal loss of buccal bone and soft tissue around implants with conical connections were lower than around those with external or internal connections. Statistically significant negative correlations were observed between initial horizontal bone thickness and changes in vertical bone and soft tissue height ( p < .05), and between initial horizontal soft tissue thickness and the change in vertical soft tissue height ( p < .05). Conclusion Implants with a conical connection preserve peri‐implant alveolar bone and soft tissue more effectively than other connection types. Furthermore, the initial buccal alveolar bone and soft tissue thickness around the implant platform may influence their vertical dimensional changes at 1 year after implant prosthesis.
