A systematic review of the survival and complication rates of fixed partial dentures (FPDs) after an observation period of at least 5 years

Abstract

Survival rates of both implants and reconstructions in combined tooth-implant-supported FPDs were lower than those reported for solely implant-supported FPDs (Pjetursson et al. 2004). Hence, planning of prosthetic rehabilitation may preferentially include solely implant-supported FPDs. However, anatomical aspects, patient centered issues and risk assessments of the residual dentition may still justify combined tooth-implant-supported reconstructions. It was evident from the present search that tooth-implant-supported FPDs have not been studied to any great extent and hence, there is a definitive need for more longitudinal studies examining these reconstructions.

Biomechanical outcomes of tooth-implant-supported fixed partial prostheses (FPPs) in periodontally healthy patients using root shape dental implants

“…Some of the possible factors are: disuse atrophy, differential energy dissipation, impaired rebound memory, rachet effect, debris impaction, fixed prosthesis flexure, mandibular flexure (only in mandible). It has been shown to occur mainly in teeth non-rigidly connected to implants 4,6,38 . However, this problem can also occur with any other attachment type 37,48 .…”

“…However, under lateral occlusal forces this compensation becomes insignificant. It should be mentioned that most of tooth intrusion cases in splinted systems were detected when non-rigid connectors were used 4,6,38 . Hence, a potential priority of one type of connector over another is still unclear.…”

“…Several authors advocate the use of a rigid connection 25,28,35,38,39 , which assumes a stiff junction between component parts of the structure with no relative motion of one part against another. The use of this type of connector reduces tooth intrusion incidence and transfers the load Meniccuci et al 28 implemented 2D and 3D FEAs to assess the stress in the bone around an implant and a tooth which are rigidly connected when a load is applied on the tooth.…”

“…Several clinical studies 3,7,9,25,51 and systematic reviews 25,38,44,45 have been implemented to find out the survival rates of implants and FPPs supported by implants and natural teeth.…”

Ten-year survival rate for cantilevered fixed partial dentures

“…This systematic review is the final one following three other reviews [1][2][3] by the same group looking at the survival and complication rates of different designs of FPD. The title of the series is slightly misleading in suggesting that the data reflect a minimum of 5 years of observation, whereas the inclusion criteria for study selection in fact required a mean follow-up time of 5 years or more.…”
