Induction and Regeneration of Cementum, Periodontal Ligament and Alveolar Bone Using Recombinant Human BMP-2 with Polylactic Acid Polyglycolic Acid Copolymer and Gelatin Sponge Complex Carrier. Investigation with Dog Fenestration Model.

Abstract

本研究は, rhBMP-2を, 担体にポリ乳酸グリコール酸共重合体/ゼラチンスポンジ複合体 (PGS) を用いてルートプレーニングした根面に移植した場合のセメント質, 歯根膜, 歯槽骨の誘導再生, および歯根吸収と骨性癒着の発現の危険性を検討する目的で, イヌに開窓状歯槽骨欠損 (5×5mm) を作製し骨欠損周囲のセメント質と歯根膜に電気メスを用いて損傷を与えた後, 対照群には担体のみを移植し, 実験群にはrhBMP-2を配合比率0.4μg/mm3で移植し, 病理組織学的観察と組織学的計測を行つた。観察期間は13~16週とした。対照群では術後4週に2部位に炎症を伴う腫脹が生じたが, 実験群は観察期間終了時まで良好であった。骨の再生率は, 実験群約97%, 対照群約81%で統計学的有意差 (p<0.05) がみられ, 骨が再生した部位には歯根膜様軟組織が生じていた。一方, セメント質の再生率は約54%と約44%で統計学的有意差はみられなかった。歯根吸収は表面吸収型のみが観察され, 歯根吸収率は実験群約29%, 対照群約'41%であった。骨性癒着は両群ともに観察されなかった。以上の結果から担体にPGSを用いてrhBMP-2を根面に移植すると, 担体のみの移植に比べ歯槽骨と歯根膜様軟組織の再生は明らかに多くなり, セメント質の再生も多くなる傾向を示し, 骨性癒着は生じないことが示唆された。
