But achieving this relationship is important only for individuals with a high smile line. The Maxillary Lateral Incisor Agenesis (MLIA) presents a challenge for the dental team. Am J Orthod Dentofacial Orthop 2016;150:416-24. Kinzer GA, Kokich VO Jr. Inclination of maxillary canines should also be adjusted so that root appearance is minimized. Some researchers classify according to hereditary form, some according to the number of missing teeth and some classify depending on the severity. Infections of tooth germ, trauma or traumatic removal of the deciduous teeth are the major environmental factors for tooth agenesis. Congenital lateral absence is one of the most common dental agenesis. With approximately one fourth of the population missing ≥1 third molar, tooth agenesis is considered a common dental anomaly. 2017). 4 Both genetic and environmental factors may result in tooth agenesis. Most genetic diseases are determined by the status of the two copies of a gene, one received from the father and one from the mother. Figure 1. However, composite build-up restorations or composite veneer restorations cannot provide the ideal reflection or translucency similar to enamel. Root canal treatments of teeth were performed in the second week after transplantation. Accordingly, the absence of 1-2 teeth is mild, that of 3-5 teeth is moderate and 6 or more teeth is noted as severe hypodontia[10]. Severe hypodontia has been reported to cause a decrease in quality of life associated with oral health. The young dental patient with maxillary lateral incisor agenesis, maxillary canine impaction, and cystic fibrosis presents considerable challenges to the dentist. Deepbite can be observed in hypodontia patients, especially when incisor teeth are missing in mandibular arch. Disorders in early stages of tooth formation may cause developmental problems or congenital absence of one or more teeth[1]. Int J Oral Maxillofac Implants. [Last accessed on 9 Nov 2018]. Oligodontia is genetic as well and is the term used to describe a condition in which six or more teeth are missing. Compare treatments taken by people with familial tooth agenesis. A common characteristic for all types of hypodontia was also shown, which is a significant increase in interincisal angle due to retroclination of maxillary and mandibular incisor teeth[20]. 2017). Eur J Oral Sci. Tooth agenesis, hypodontia, oligodontia, genetic, space closure, space opening. X-Linked type 1 … Nevertheless, orthodontic treatment can facilitate any restorative treatment that may be required. Tooth Agenesis, Selective, X-Linked, 1: Genetic mutations can result in the absence of various teeth. A: Intraoral frontal view before treatment; B: intraoral occlusal view before treatment; C: intraoral frontal view after completion of orthodontic treatment. In such cases, removable appliances with anterior bite planes can be used in maxillary arch for mandibular molar extrusion in early stages. Tooth agenesis of permanent teeth was found in 2200 persons on examination of a total of 31,992 Japanese subjects. The prevalence of anodontia is unknown.

The diagnosis can be set on at average 9 years of age. It is suggested that patients’ age, type of skeletal and dental malocclusion in sagittal and vertical dimensions, crowding in both dental arches and facial profile should be analyzed before choosing the best treatment alternative[25]. Golden ratio or Bolton analysis can be used for measurement of edentulous spaces in patients with either unilateral or bilateral congenitally missing maxillary lateral incisors[26]. Comprehensive treatment covering a long period of time must be planned in hypodontia cases to achieve optimum results for a lifetime. Rakhshan V, Rakhshan H. Meta-analysis and systematic review of the number of non-syndromic congenitally missing permanent teeth per affected individual and its influencing factors. This can help eliminate the infection and save your tooth. 7th ed. Treatment includes multidisciplinary team approach of pedodontists, orthodontists, oral and maxillofacial surgeons, and prosthodontists to restore aesthetics, functional, and psychological reasons depending on the severity of the condition and patient's perceived need for care The treatment not only improves speech and masticatory function, but also has psychological implications that may greatly help in … The ideal reflection or translucency similar to enamel a condition characterized by smaller normal..., Inc. all Rights Reserved anomaly characterized by the ages 12 to 14, Dhamo,!
