Management of congenitally missing second premolars in a growing child

Abstract

The second premolars have the highest incidence of congenital absence, after the third molars. The problem resides not in the prevalence of congenitally missing premolars but in the selection of a treatment plan that will yield the best results over the long term. The present study reports a case of a 14 year old female patient with bilaterally congenitally missing second mandibular premolars with associated crowding of teeth. The case has been managed using a multi-speciality approach, in which both deciduous mandibular second molars were sectioned and the distal half retained. The retained half was prepared to receive a full coverage restoration which was contoured as a premolar. The space created was then utilized to correct the crowding by fixed orthodontics. A two year follow up shows retained distal half of the deciduous mandibular second molar with correction of crowding and space closure.

Methods of treatment of premolar agenesis: a literature review

“…The remaining space was closed with fixed appliance. During the two-year followup, no complications were observed (44).…”

“…In 80% of the examined patients, permanent molars were mesialised without tilting and mesiorotation. No midline shift was (44,45). Połowa DM2 poddanego hemisekcji może również stanowić uzupełnienie długoczasowe.…”

“…Po leczeniu endodontycznym DM2 korona zęba została odbudowana do morfologii zęba przedtrzonowego, a luka została zamknięta ortodontycznie. W okresie dwuletniej obserwacji nie zaobserwowano żadnych powikłań (44). W badaniach Valencia i wsp.…”

Alveolar Bone Preservation Using an Orthodontic Mini-implant in an Adolescent Patient with Multiple Missing Teeth

“…5,6 The first treatment option is orthodontic space closure of the site of the missing tooth, and the second is the maintenance of space for prosthetic treatment. 7 Prosthetic treatment with dental implant placement in the growing adolescent is contraindicated because the growth of the alveolar bone causes dental implant prosthesis infraocclusion. 8 In the first option, the progress of space closure can be performed through skeletal and soft-tissue analysis when facial esthetics and occlusion are expected to improve.…”
