Ultrashort Implants, Alternative Prosthetic Rehabilitation in Mandibular Atrophies in Fragile Subjects: A Retrospective Study

Abstract

This study aimed to evaluate the effectiveness of using ultrashort implants in the rehabilitation of jaws of fragile patients. The aim of the study was to retrospectively evaluate the survival rate of full-arch prosthetic rehabilitation on ultrashort implants, length 4 mm, 4 mm in diameter in the premolar and canine area and 4.5 mm in diameter in the molar area, with the insertion torque of 60 Nw and immediate loading. Nineteen patients were evaluated for 3 years clinically and radiographically. The significant majority of the patients at the 3 year follow-up (T4) presented a stable and functional implant-supported prothesis, and the survival rate of the implants was 85%, with a loss of 16 implants on 114 implants. The combination of the innovative implant surfaces and the correct project of the prostheses, with the related implant connection, determined a different timing in the therapy, allowing to obtain an immediate loading, which is currently demanded by patients. This and recent reports on short and ultrashort implant usage in atrophic jaws offer a good solution in critical cases. In conclusion, within the limits of the study, the full-arch rehabilitation with immediate loading on ultrashort implants showed good results with few postoperative complications and related low biological cost.

Bio-Morphological Reaction of Human Periodontal Ligament Fibroblasts to Different Types of Dentinal Derivates: In Vitro Study

“…Consequently, the periodontal ligament adhesion to the alveolar bone can decrease with mobility or dental exfoliation [2,3]. After dental extraction, the residual alveolar bone crest proceeds to a resorption process, which in some cases cannot permit the implant placement necessary to rehabilitate the created edentulism with a fixed prosthetic device [4,5].…”

Ultrashort implant in the upper jaw, an alternative therapeutic procedure after the failure of the sinus lift: a case report

“…A recent retrospective study evaluating the implant success rate of 50 ultra-short dental implants after a follow-up of 8-10 years reported a success rate of 94% and that the ultra-short implants proved to be a reliable solution for prosthetic restoration in patients with severe alveolar bone atrophy 23 . Another study reported that in patients who underwent the rehabilitation of the complete arch using ultrashort implants, the critical rehabilitation issues occur in the first week and after four months following implant placement together with the prosthetic load 22 . The presented a case showed a patient successfully treated with an ultra-short implant of 3 millimeters after the failure and complication of a sinus lift, with a total follow-up of 36 months, confirming the reliability of the ultra-short implant as a valid and effective therapeutic option for severe atrophy bone.…”

Use of the electrical device on dental implant�s bacterial biofilm: a preliminary in vitro study

“…The treatment of choice for the resolution of both partial and total edentulism of patients consists in the use of dental implants (1)(2)(3)(4)(5). In recent decades, their use has exponentially evolved.…”
