ABSTRACT

Loss of teeth often leads to buccal plate bone left unsupported along with lack of blood supply further causing resorption of alveolar bone for which a myriad of procedures is available to refrain post-extraction bone loss including immediate implant. This study is aimed to evaluate radiographic outcomes of the alveolar ridge following immediate implant placement associated with the use of a calcium phosphosilicate (CPS) putty bone graft placed between the implant and the inner surface of the buccal alveolar plate. 15 implants were placed with a lingual/palatal orientation immediately after atraumatic extraction. The gap between the internal surface of the socket and the implant surface gap was filled with a CPS putty bone graft. Finally, a healing abutment was placed. CBCT analysis was carried out after immediate implant placement and 6 months post-operatively to assess the horizontal bone changes at the implant platform (L1), the mid implant (L2), and implant apex (L3) levels. Vertical bone height was measured from the implant platform to the buccal bone crest. CBCT analysis was assessed for buccal bone width at L1, L2, and L3 and was decreased at 6 months, similarly palatal bone width at L1 showed no change whereas L2, and L3 showed a decrease at 6 months along with bucco-palatal bone width significantly decreased at 6 months and lastly a minimal decrease was observed in vertical facial height at 6 months. The results were statistically significant. Minimal horizontal peri-implant buccal, palatal, and bucco-palatal bone dimensional changes were noted at 6 months after placement of immediate implant and use of Calcium Phosphosilicate putty bone graft. Moreover, minimal vertical facial bone height loss was observed.
