AIM One of the critical aspects of esthetic dentistry is creating geometric or mathematical proportions to relate the successive widths of the anterior teeth. The golden proportion, the recurring esthetic dental (RED) proportion, and the golden percentage are theories introduced in this field. The aim of this study was to investigate the existence of the golden proportion, RED proportion, and t...

OBJECTIVE The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 ...

PURPOSE The objective of this study was to assess the pattern of permanent teeth present in a self-selected sample of 17 female and 35 male patients with ectodermal dysplasia presenting for treatment with dental implants. METHODS Mean age of sample: 18.7 years, age range: 5.9 to 60.9 years. Panoramic radiographs were examined independently by two investigators to determine the permanent teeth...

OBJECTIVE To compare the anchorage effects of the implants and the headgear for patients with anterior teeth retraction in terms of incisor retraction, anchorage loss, inclination of maxillary incisors, positional change of maxillary basal bone, and treatment duration. MATERIALS AND METHODS An electronic search for relative randomized controlled trials (RCTs) prospective and retrospective con...

Dental anomalies affecting the teeth are relatively common. Simultaneous occurrence of multiple dental abnormalities in a single tooth is uncommon and relatively rare. One such abnormality routinely encountered in dental clinics is the talon cusp. It is also referred to as dens evaginatus, characterized by the presence of an accessory cusp-like structure projecting from the cingulum of anterior...

BACKGROUND A facial bone (<2 mm) overlying maxillary anterior teeth may be prone to resorptive processes after extraction and immediate implant placement. A thin bone contributes to risk of bone fenestration, dehiscence, and soft-tissue recession. This study measures the distance between the cemento-enamel junction (CEJ) and alveolar bone crest and the thickness of facial alveolar bone at point...

A 51-year-old woman who worked as a company sales representative was concerned about the deteriorating condition of her anterior teeth. On presentation, the appearance of her anterior teeth was less than ideal, and she requested treatment to improve the situation. Her medical history was noncontributory, but intraoral examination revealed excessive diastema between the maxillary central incisor...

STATEMENT OF PROBLEM In rehabilitating edentulous patients, selecting appropriately sized teeth in the absence of preextraction records is problematic. PURPOSE The purpose of this study was to investigate the relationships between some facial dimensions and widths of the maxillary anterior teeth to potentially provide a guide for tooth selection. MATERIAL AND METHODS Sixty full dentate Mala...

PURPOSE The purpose of this study was to compare the width ratio of maxillary anterior teeth according to age in the Korean population and to evaluate the maxillary central incisor width-to-length (W/L) ratio, given differences in age and gender. MATERIALS AND METHODS Ninety-three Korean adults were divided into 3 groups (n = 31) by age. Group I was 20 - 39 years old, Group II was 40 - 59 yea...

The case report presented here is of a 4-year-old girl with severely decayed maxillary anterior teeth. After root canal treatment, the primary maxillary central and lateral incisors were reinforced using polyethylene fiber-reinforced composite resin short posts and restored using celluloid strip crowns. The technique described here offers a simple and effective method for restoring severely dec...
