摘要


大臼齒牙周病的治療常受限於牙根分叉的結構複雜,導致治療的癒後無法預測。病人可能因為喪失大臼齒造成咀嚼食物不方便。雖然傳統的牙橋或活動假牙可以解決這問題,但卻相對地傷害了健康的鄰牙。有了牙科植體後,似乎是病人的一項福音。植體發展之初多是應用在多支植體的病例,成功率都很高。為因應病人的需求,很多植體也需應用在單顆缺牙的重建,但文獻回顧中對於大臼齒單顆植體的應用報告卻較少,主要受限於大臼齒解剖位置(包括下顎齒槽骨神經、上顎竇)及後牙區域骨頭密度稀疏,而無法廣泛應用。本篇文章主要就是要回顧單顆植體應用於大臼齒區域的研究,並討論其應用上的併發症。

There are several factors that affect the prognosis of periodontally-diseased molars. These factors make our periodontal treatments less predictable. We can give the patient, who lost his molar, a bridge or a removable partial denture. By doing this, some healthy tooth structures must be lost. When implants are used, they become a treatment alternative for dentists and patients. In the beginning, these implants were used in full edentulous patients and were splinted together, and had very high success rate. Single molar implant may be more difficult due to the limitation of anatomic condition, such as maxillary sinus, inferior alveolar canal and low bone density of this area. Recently, several clinical studies indicated that the success rate for single molar implant therapy is higher than 90%. The purpose of this paper is to review the clinical studies in single implants used in molar regions. The determinants of clinical success of single implants are evaluated. The biological and technical complications of single implants are also discussed.
