The lack of the periodontal ligaments around the implants results an ankylotic fixation. The mobility of the osseointegrated implants is only one tenth of the mobility of the natural teeth. To connect a natural tooth and an implant as abutments in a fixed restoration is a special problem in the dentistry. The aim of this study was to examine whether connecting of implants and natural teeth has any disadvantages for the abutment either implant or natural tooth. Furthermore we wanted to know if an overloading of the opposing tooth could occur because of the stiffness of the implant-bone connection. 21 partially edentulous patients, who were treated with implant supported bridges using the DenTi implant system which includes screw-shaped, commercially pure titanium implants, were examined. Plaque, calculus, gingival index, probing depth and bleeding on probing were recorded around the implants and the teeth. Mobility, sound on percussion were examined as well. In this study no disadvantageous effect of connecting teeth to implants as abutments by fixed partial dentures was found. There was no sign of a harmful effect of the implant to the opposing teeth either. The tooth-to-implant bridges function in their biological environment without affecting it adversely.
种植体周围缺乏牙周韧带会导致骨结合固定。骨结合种植体的动度仅为天然牙动度的十分之一。在固定修复中，将天然牙和种植体作为基牙连接起来是口腔医学中的一个特殊问题。本研究的目的是检验将种植体与天然牙连接对基牙（无论是种植体还是天然牙）是否有任何不利影响。此外，我们想了解由于种植体与骨的连接刚度，对颌牙是否会出现过载情况。对21例部分牙列缺损患者进行了检查，这些患者使用包括螺旋形商业纯钛种植体的DenTi种植系统进行种植支持式桥修复。记录种植体和牙齿周围的菌斑、牙石、牙龈指数、探诊深度和探诊出血情况。还检查了动度和叩诊音。在本研究中，未发现通过固定局部义齿将牙齿与种植体连接作为基牙有任何不利影响。也没有种植体对颌牙产生有害影响的迹象。牙-种植体桥在其生物环境中发挥功能，而不会对其产生不利影响。
