Immediate rehabilitation of the edentulous jaws with full fixed prostheses supported by four implants: interim results of a single cohort prospective study

Abstract

The present preliminary results from a relatively large sample size suggest that the present technique can be considered a viable treatment option for the immediate rehabilitation of both mandible and maxilla.

Clinical aspects in the treatment planning for rehabilitation with overdenture and protocol-type prosthesis

“…The anatomical factors that have the greatest influence on the maintenance and prognosis of any prosthetic rehabilitation using dental implants are bone quality and quantity [13][14][15][16][17] . The following parameters should be investigated during the extraoral and intraoral clinical examination to select the appropriate type of prosthesis…”

“…As for the bone anatomy, in order for a suitable number of dental implants be placed in the ideal positioning there must be good bone quality (both width and height) [14][15][16][17] . Bone quality around the implant affects its resistance under mechanical loading conditions 14,17 .…”

“…Depending on the selection of the system attachments, the retention attachments, and the scattering of the spreading of the implants, the bite force exerted by the overdenture on the implants and on peri-implant bone as well as the amount of force that will be absorbed by the mucosa can be controlled 14,21 .…”

“…The objective of this study was, through a literature review, to gather information about planning for prosthetic rehabilitation using Branemark protocol and overdenture prostheses aiming for an effective and Planejamento de Prótese Overdenture e Protocolo the number, diameter, and length of the implants, and by the antagonist arch 14-16. The treatment planning for rehabilitation with overdenture or protocol-type prosthesis is based on the mechanical loading it will be subjected to 14. Depending on the selection of the system attachments, the retention attachments, and the scattering of the spreading of the implants, the bite force exerted by the overdenture on the implants and on peri-implant bone as well as the amount of force that will be absorbed by the mucosa can be controlled 14,21 .…”

“…Moreover, in the scientific literature, the advantages of overdentures are also related the ease of cleaning and better restoration of facial profile 12,15-16. However, an overdenture prosthesis more carefully and accurately designed and fabricated than a protocol-type prosthesis has been reported in the literature 2,4-5,9-10,14,16 . Overdenture design and placement must include all parameters and factors used in conventional total prosthesis 2,4-5,9-10, 14,16,[18][19] . Among the overdenture retention attachments available, the bar-clip system provides greater degree of stability and therefore higher patient satisfaction [10][11][12][16][17]19 .…”
