Evaluation of Alveolar Bone Dimensions and Root Positioning of Anterior Teeth in the Maxilla.

Buccal bone walls present significant resorption after tooth extraction, possibly related to the smaller bone thickness, length, and the sagittal position of the root, as well as the bone morphology. The goal of the present study was to measure the thickness of the cortical bone of the vestibular and palatal walls in the anterior maxilla by means of CBCT images. Measurements were taken from CBCT scans of 300 maxillary anterior teeth from 50 patients (25 women, 25 men) aged 18 to 30 years.

Characteristics of periodontal biotype, its dimensions, associations and prevalence: a systematic review.

Aim: The objectives of this review were as follows: What are characteristics used to define various forms of periodontal biotypes? What are their anatomic dimensions in relation to the definition? In addition, what is the association between these various characteristics in relation to the periodontal biotypes? Furthermore, what is the prevalence of various forms of periodontal biotypes in the population?

Material And Methods: The PubMed-MEDLINE, the Cochrane-CENTRAL and EMBASE databases were searched through up and till June 2013 to identify any appropriate studies regarding the aim. Appropriate studies were those reporting characteristics of various forms of periodontal biotype and its dimensions. These characteristics were gingival thickness (GT), gingival morphotype (GM), tooth dimensions (TD), keratinized tissue (KT) and bone morphotype (BM).

Significance of crown shape in the replacement of a central incisor with a single implant-supported crown.

Objective: When utilizing a single implant-supported crown to replace a central incisor, understanding the final shape of the implant restoration is an important factor to help achieve a successful esthetic outcome. In today's dentistry, tooth shape is a critical factor when dental implant prostheses are considered in the esthetic zone. The major esthetic goal for this type of restoration is to achieve the closest possible symmetry with the adjacent tooth, both at the soft and at the hard tissue levels.

Anterior maxillary and mandibular biotype: relationship between gingival thickness and width with respect to underlying bone thickness.

Purpose: : Periodontal biotype is considered to be a significant factor related to successful dental treatments. The purpose of this study was to determine the relationship between gingival thickness (GT) and width with respect to the underlying bone thickness in the maxillary and mandibular anterior sextant.

Materials And Methods: : Overall, 180 anterior teeth within healthy patients were assessed.

Analysis of the shapes of maxillary central incisors in a Caucasian population.

The purpose of this study was to objectively define and quantify triangular, square, and square/tapered maxillary central incisors. In this study, the shape of maxillary central incisor crowns was investigated in 100 healthy individuals. The results showed that when the contact surface/crown length ratio is less than 43%, the tooth is triangular in shape; when the ratio is more than 57%, the tooth is square in shape; and when the ratio is between 43% and 57%, the tooth is defined as square/tapered.

Intraosseous anchorage of dental prostheses: an early 20th century contribution.

A thorough literature review of root form implants yielded a paucity of information regarding the true pioneers of this discipline. Numerous articles have been written on the history of endosseous implants, although little information is available describing the individuals to whom we attribute the major developments in implant dentistry. This article will present information regarding significant contributors to modern-day implant dentistry.

Connective tissue graft: a classification for incision design from the palatal site and clinical case reports.

A classification system for connective tissue graft incisions is proposed. It categorizes the design of the palatal incision into three classes. In addition to the basic classification, two subclasses are mentioned in this article.
