  • 1. MANAGEMENT OF ACONGENITALLY MISSINGLATERAL INCISORS Zeina Abou Zour
  • 2.  The maxillary lateral incisor is the 2nd most frequently missing tooth after the mandibular second premolar (not including the third molars) 20% of all missing teeth are the maxillary lateral incisors. Agenesis of both maxillary lateral incisors(bilateral) is more common then agenesis of only one (unilateral).(Symons,1991) Females are more affected then males.(Bergstrom,1977)
  • 3. Agenesis of the maxillary lateral incisor is also linked with other dental anomalies such as : 1) Agenesis of other permanent teeth. 2) Microdontia of the contra lateral maxillary lateral incisor (Peg- shaped) and other permanent teeth. 3) Palatally displaced canines. 4) Distal angulation of the mandibular 2nd premolars.
  • 4. Therefore the absence of one or more maxillary lateral incisor introduces a potential imbalance in the maxillary dental arch, obvious impact on facial aesthetics and it requires a complex and multidisciplinary treatment approach.
  • 5.  The 2 major treatment approaches for congenitally missing lateral incisors are: 1) Space Closure (Canine subistution) 2) Space Opening (To allow prosthodontic replacement)
  • 6. Several factors need to be considered when deciding whether toclose the space left by a maxillary lateral incisor or to open thespace for a prosthetic tooth: 1) The presence of skeletal malocclusion. 2) Amount of crowding. 3) Facial profile. 4) Canine shape and color. 5) Lip level and gingival contour.
