Telescopic Overdenture and Implant Supported Fixed Partial Denture: A Pragmatic Treatment Approach

Abstract

This case report presents a patient who had been rehabilitated with a telescopic overdenture and implant supported fixed partial denture (ISFPD). The treatment process was as follows: (1) fabricating telescopic crowns and overdenture prosthesis for the lower jaw and a temporary complete denture for the upper jaw, (2) using the temporary denture as diagnostic and surgical guide to optimize dental implant placement, and (3) fabricating ISFPD for the upper jaw. Using the patient's existing or temporary denture not only serves as an alternative surgical guide to calibrate the dental implant locations but also helps to finish the restoration at desired dimension, size, and anatomic form.

Effect of telescopic distal extension removable partial dentures on oral health related quality of life and maximum bite force: A preliminary cross over study

“…The patient satisfaction and bite force with telescopic PRDPs (with or without cantilevered extensions) was higher than conventional PRDP. This may be due to tooth supported telescopic PRDPs provided better retention and stability, stable occlusion, and chewing function due to the conservation of proprioception feedback . In contrast, the combination clasp used with conventional PRDPs have a flexible wrought wire retentive arm which minimize retention and stability of the PRDPs and therefore may had a negative effect on patient satisfaction.…”

“…Moreover, these prostheses provided rigid splinting action, and better distribution of stresses between teeth and soft tissues, decreased the proportion of most traumatic lateral forces, transmitted the occlusal forces in the direction of the long axis of the abutment teeth, and increased prosthesis stability particularly in patients with atrophied ridges . Telescopic PRDPs are also more aesthetic and hygienic than conventional removable partial dentures . Polansky et al reported that the use of telescopes with appropriate maintenance and oral hygiene did not lead to any deterioration of the periodontium.…”

“…This may be due to tooth supported telescopic PRDPs provided better retention and stability, 12 stable occlusion, and chewing function due to the conservation of proprioception feedback. 10 In contrast, the combination clasp used with conventional PRDPs have a flexible wrought wire retentive arm which minimize retention and stability of the PRDPs and therefore may had a negative effect on patient satisfaction. The frictional contact at the intersurface between both primary and secondary copings, together with nearly parallel coping walls ensured adequate retention and stabilization of telescopic PRDPs.…”

“…The splinting action of telescopic restorations occurred when multiple outer and fixed inner telescopic crowns engage each other in situ . Telescopic prostheses may result in excellent oral hygiene maintenance, stable occlusion, and satisfactory chewing function due to preservation of proprioception feedback . Moreover, telescopic crown‐retained PRDPs have had positive impacts on patients' well‐being and quality of life, especially in patients with few remaining teeth .…”

“…8 Telescopic prostheses may result in excellent oral hygiene maintenance, stable occlusion, and satisfactory chewing function due to preservation of proprioception feedback. [9][10][11] Moreover, telescopic crown-retained PRDPs have had positive impacts on patients' well-being and quality of life, especially in patients with few remaining teeth. 12 However, the telescopic anchors are technically challenging in terms of transfer, milling technique and passive fit.…”
