Delayed expansion of atrophic mandible (deam): a case report

2017

Purpose. The present case report presents the clinical results of delayed expansion of mandibles by ultrasonic surgery in case of mono edentulous. Materials and methods. The patients with a residual alveolar ridge thickness between 2,3 and 4,1 mm in the coronal area of posterior mandible was threated. In the first stage, four linear corticotomies were carried out by ultrasonic surgical device; bone expansion was not performed. After 4 weeks, in the second stage, adequate bone expansion, without compromising cortical vascularisation, by utilising a combination of scalpel, thin chisels and threaded osteotomes was achieved and one implant was placement, after filling the gaps with a cortico bo…

Immediate Postextractional Implant Insertion in Posterior Maxilla. Therapeutic Attitude

2020

Abstract The immediate postextractional implant insertion is a specific way of surgical approach to implanto-prosthetic treatment. This article addresses the indications, advantages, and surgical techniques of immediate postextraction insertion, illustrated with a clinical case. Objectives: presentation of the indications, advantages and surgical procedure of immediate postextractional implant insertion. Materials and methods: The present study considered the presentation of a case in which we opted for the insertion of implants immediately postextractionally as a therapeutic attitude. Results and discussions: The advantages and disadvantages of this therapeutic technique were represented a…

Radiographic healing patterns after tooth-borne distraction in canine model

2020

Background The osteogenesis distraction technique applied to the craniofacial skeleton is an alternative treatment for dentofacial deformities. Despite the advantages of tooth-borne distractors, few studies have evaluated their clinical implementation in sagittal dentoskeletal deformities. This study aimed provide a radiographic assessment of the effect of two different activations of tooth-borne distraction in the lengthening of the mandible in canines. Material and Methods Ten male beagle dogs, approximately one year old, were used for this experimental study. Three remained as a control group and seven underwent a mandibular tooth-borne distraction protocol with single daily activation i…

Altered passive eruption (APE) : a little-known clinical situation

2010

Gummy smile constitutes a relatively frequent aesthetic alteration characterized by excessive exhibition of the gums during smiling movements of the upper lip. It is the result of an inadequate relation between the lower edge of the upper lip, the positioning of the anterosuperior teeth, the location of the upper jaw, and the gingival margin position with respect to the dental crown. Altered Passive Eruption (APE) is a clinical situation produced by excessive gum overlapping over the enamel limits, resulting in a short clinical crown appearance, that gives the sensation of hidden teeth. The term itself suggests the causal mechanism, i.e., failure in the passive phase of dental eruption, tho…

The TORONTO PROSTHESIS, an appealing method for restoring patients candidates for hybrid overdentures: A case report

2012

The implant is a therapeutic resource in constant evolution, and the different types of implants and techniques have been increasingly used in cases of both fully or partially edentulous patients. In some cases they provide more conservative treatment, and in others better stability, retention, and function. To achieve a satisfactory result, there are several factors that should be taken into account: the type and quality of the bone, bone density, the placement location of implants, retrievability of restorations, the patient’s motivation, and economic issues. Trainees should be aware of the limitations of the techniques that can be used for successful prosthetic rehabilitation. This work …

Radiographic Investigation of Location and Angulation of Curvatures in Human Maxillary Incisors

2008

The aim of this radiographic study was to evaluate the degree and location of root canal curvatures of human maxillary incisors. A total of 286 extracted human maxillary incisors (145 central and 141 lateral incisors) were included in this investigation. Exclusion criteria were teeth with extensive carious lesions, restorations, and root canal treatment. For this in vitro study, the teeth were fixed in a special device and digitally x-rayed with the parallel technique. The distances from the cementoenamel junction (CEJ) to the first curvature and the according angle were recorded. The results were analyzed descriptively, and p values were calculated with the Wilcoxon Mann-Whitney test. The …
