An inventory of mandibular fractures associated in atrophic edentulous mandibles

Abstract

hydroxyapatite coated implant system was employed in this study. The patients were followed up for a median of 31.3 months (range, 4 to 103 months). Results: There were no failures in the cases of immediate implant placement. Findings and Conclusions: Originally, there was quite a difference in the shape between extraction socket and implant, so a certain consideration for implant site selection was needed to establish the initial fixation. Furthermore, meticulous cleaning, socket curettage/debridement was also necessary to remove infectious areas in extraction sockets of the compromised teeth. Finally, successful immediate implant placement would be promised when fulfilling certain inclusion criteria.http://dx. Background:The rehabilitation of atrophic maxilla is a challenge for maxillofacial surgeons. Bone grafts, short implants zygomatic fixtures, has show good results, however on maxillary atrophy associated with hypoplasia, anterior cant lever can lead the rehabilitation to mechanical failure. Objective: The aim of this paper is to report the surgical protocol adopted to the correction of edentulous atrophic and hypoplastic maxilla. Methods: Three patients (one male and two females) with sagittal maxillary deficiency and class V (Cawwod and Howell) alveolar atrophy were selected. The patients were rehabilitated by means of Le Fort I osteotomy associated with zygomatic implants and immediate loading. All patients were able to receive fixed prosthesis 3 days after the surgery. Results: All implants remain healthy and in function. One prosthesis required maintenance on the abutments screws six months after surgery, after that no other problem occurred. Conclusion: Maxillary reposition by Le Fort I osteotomy associated with zygomatic implants can be an alternative to bone grafts on rehabilitation of atrophic maxilla with maxillomandibular disrepancy.http://dx.

Sandwich osteotomy in atrophic mandibles: A retrospective study with a 2‐ to 144‐month follow‐up

“…In our study, the average residual height above the nerve in full edentulism was only 3.2 mm and the nerve actually went beneath the mucosa in some extreme cases. However, low mandible height (10 mm or less measured at the symphysis) is at high risk of fractures (Soehardi, Meijer, Manders, & Stoelnga, ). One fracture occurred in a mandible of 8.2 mm height.…”

Bone augmentation followed by implant surgery in the edentulous mandible: A systematic review

“…The extremely atrophic mandible is also at risk of fracture after a mild trauma and is most common among elderly people, in which bone healing is less optimal. 3,4 The elderly are more likely to suffer from comorbidity and the effects of polypharmacy. Epidemiological evidence shows that an edentulous mandible with <10 mm of radiological height (based on measurements on a panoramic radiograph) has a higher risk of…”

“…When lack of attached alveolar mucosa exists with or without a surplus of buccal and lingual soft tissues, dental implant placement can be challenging. The extremely atrophic mandible is also at risk of fracture after a mild trauma and is most common among elderly people, in which bone healing is less optimal . The elderly are more likely to suffer from comorbidity and the effects of polypharmacy.…”

“…The elderly are more likely to suffer from comorbidity and the effects of polypharmacy. Epidemiological evidence shows that an edentulous mandible with <10 mm of radiological height (based on measurements on a panoramic radiograph) has a higher risk of complications and failure after dental implant surgery . Increasing the bone volume of the mandible by means of bone augmentation is of importance in these cases, because it enables adequate dental rehabilitation in these patients.…”

Short implants to support mandibular complete dentures - photoelastic analysis

“…Therefore, the knowledge of the biomechanics of dentures supported by short implants is necessary to increase the predictability of this treatment and avoid complications. 29 The substantial outcomes obtained with short implants conduced us to test the biomechanical behaviour of short implants when used to support complete prosthesis. This would contribute to the treatment planning involving patients with severe mandibular atrophy, to increase the predictability, and avoid large bone reconstructions.…”
