BACKGROUND: Aim of this work is to underline the prosthodontics components features of two different overdenture retention systems on dental implants The use of titanium, dental implants for replacing missing teeth is today considered to be a predictable procedure giving the patients aesthetic and function for long time.
METHODS: Fem investigation and Von Mises analyses have been applied for evaluating the stress distribution over two different prosthodontics retention systems. Two models with the ball attachment and with the Locator ® systems have been created and put on simulated chewing stresses.
RESULTS: the two investigated systems were subjected to axial and oblique forces and both guaranteed good results over simulated masticatory cycle. However it seems that locator system better responded to the overall load distributions.
CONCLUSIONS: Clinicians should choice the better prosthetic solution compared with the ridge they want to prosthetically restore. Both retention systems offers long term success if applied following the manufacture guide limitations and suggestions.
