Abstract

Abstract: Due to the prevalence of insufficient remaining alveolar bone or excessive expansion of the incisive canal in the maxillary central incisor region, the stability of implants may be affected. Titanium implants into incisor canals may cause a series of complications such as nasopalatine canal cyst, postoperative short-term sensory disturbance, implant failure, and so on. In order to solve this clinical problem, this study explored and practiced the application of bone substitutes in the incisive canal for implant placement. The application of various bone substitutes in the incisive canal for implant placement was reviewed and analyzed in this paper. Combined with a clinical case of bone substitutes used in the incisive canal for implant placement, the clinical effect of bone substitutes in the incisive canal for guided bone regeneration and implant placement was demonstrated. The implant osseointegration was good and the aesthetic outcome was satisfactory. Re-examination after 6 months showed that the soft tissue around the implant was stable and there was no obvious bone resorption. The use of bone substitutes to guide the internal osteogenesis of the incisive canal can provide three-dimensional bone support for the implant, which is helpful in obtaining good implant stability and anterior aesthetic effect. It has been reported in the literature that different materials, such as autogenous bone, allograft bone or mixed bone substitute, or autogenous bone mixed bone substitute, can achieve the internal osteogenesis of the incisive canal.
