摘要

一般在拔牙後，齒槽骨多少都會吸收，尤其是在唇額側的骨板遭到破壞時，吸收的程度更是嚴重，因此往往使在牙醫師在為病人製作贋復物時非常地困擾！拔牙窩洞的保存，尤其在強調足夠的骨量的植牙治療，對於假牙在製作上的影響更是重要。目前在拔牙窩洞的保存上，有使用人骨或人骨替代物，導引再生手術或合併導引再生手術與骨粉／骨替代物等方法。本病例報告中，病人由於左上側門牙斷裂，拔牙時發現窩洞的唇側破壞達三分之二，繼植入人體乾燥骨粉與膠原蛋白加以保存，於一年後植牙，並完成補綴治療。同時在植牙時取一新生骨之樣本作組織學之觀察，發現新生骨完整，而所有的脫鈣乾燥骨均完全被新生骨取代。

It was known that alveolar ridge will be resorbed after tooth extraction. If the bony plate was not intact, the resorption will be more severe and made the following restoration difficult. Socket preservation with bone or bone substitutes, GTR, or combination of the two, had been used to augment the extraction socket. This case report described about the restoration of a fractured upper left lateral incisor. The labial plate of the lateral incisor was damaged, too. After the extraction, the collapsed socket was grafted with DFDBA and Collaplug. 12 months later, an implant was installed. The augmented ridge was well maintained, about 6 mm bucco-palatally. At the implant installing surgery, a 1 mm X 5 mm bone core was obtained by a 3 mm trephine and send for histological evaluation. The histological specimen showed a bone core composed of vital bony tissue no remaining graft material was found. Six months later, the prosthesis was completed and the restoration was followed for more than one year. The clinical parameters were remained stable.
