Finite Element Stress Analysis of Tooth‐to‐Implant Fixed Partial Denture Designs

Abstract

Based on the similarities in both the patterns of stress contours and the stress values generated in the two models, advocating a nonrigid connection because of a biomechanical advantage may be erroneous.

Tooth-Implant Connection: A Review

“…Especially, the load on the implants show rise with the increase of pontic number. is is the proof of supportation of the prosthesis by the implants [12,24]. Short-term clinical success in tooth-implant-supported and implant-supported prosthesis is similar.…”

“…Splinting of teeth will decrease the complication which may occur in long term, if contacts in posterior region are not hindered with prosthesis or skeletally in lateral movements. In addition, connection of natural teeth abutments decreases the incoming load on each support by dissipation [12,13]. Increase in number of teeth which are connected decreases the movement of prosthesis.…”

“…Akça et al (2006) [22], concluded that marginal bone surface resorption amount is negligible in rigid connection of �xed prosthesis. ere are lots of researches to refer and describe rigid implant-tooth connection in the current literature [12,23]. Teeth-supported prosthesis with rigid connection have similar mobility with implant-tooth supports bridge.…”

“…Barely, occlusal contacts must be modi�ed to direct loads to natural teeth and abstain in overloading on implant. at is why; immobile abutment requirement is one of the important criterias in connecting implant to natural teeth in clinical practice [12,15].…”

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

“…However, there is no clear consensus regarding the effectiveness of this type of connectors because of the potential clinical hazard of natural tooth intrusion 5 . Several studies reported no significant difference between rigid and non-rigid connector types 12,18 .…”
