Application of interconnected porous hydroxyapatite ceramic block for onlay block bone grafting in implant treatment: A case report (Review)

Abstract

Abstract. Autogenous block bone grafting as treatment for alveolar ridge atrophy has various disadvantages, including a limited availability of sufficiently sized and shaped grafts, donor site morbidity and resorption of the grafted bone. As a result, interconnected porous hydroxyapatite ceramic (IP-CHA) materials with high porosity have been developed and used successfully in orthopedic cases. To the best of the author's knowledge, this is the first report of clinical application of an IP-CHA block for onlay grafting for implant treatment in a patient with horizontal alveolar atrophy. The present study performed onlay block grafting using an IP-CHA block to restore bone volume for implant placement in the alveolar ridge area without collecting autogenous bone. Dental X-ray findings revealed that the border of the IP-CHA block became increasingly vague over the 3-year period, whereas CT scanning revealed that the gap between the block and bone had a smooth transition, indicating that IP-CHA improved the process of integration with host bone. In follow-up examinations over a period of 5 years, the implants and superstructures had no problems. An IP-CHA block may be useful as a substitute for onlay block bone grafting in implant treatment.

Assessment of stem cell viability in the initial healing period in rabbits with a cranial bone defect according to the type and form of scaffold

“…Autogenous bone is recognized to be the gold standard as a graft material due to its osteogenic, osteoinductive, and osteoconductive properties [2]. The disadvantage of autogenous bone lies in its quick resorption after transplantation, lower space maintenance, and the need for an additional surgical procedure during harvest [34]. Conversely, synthetic bone functions well as a space maintainer and scaffold, but has no or limited osteogenic and osteoinductive ability [5].…”

Potensi Hidroksiapatit dari Tulang Ayam Sebagai Pelapis Implan Gigi

“…Semakin besar luas permukaan, semakin kuat efek permukaannya, seperti aktivitas permukaan dan kapasitas adsorpsi permukaan. HAP hasil sintesis dapat digunakan untuk proses adsorpsi yang berbeda (Kwon et al, 2015;Ohta et al, 2017;Zhu et al, 2018). HAP dengan struktur mesopori dapat diserap dan meningkatkan ikatan yang lebih kuat ke tulang.…”
