Clinical management of the congenitally missing maxillary lateral incisor and mandibular second premolar: a clinical perspective

The decision to close maintain, or open space at the agenesis sites of the maxillary lateral incisor and mandibular second premolar is generally based on several factors, including the class of malocclusion, skeletal pattern (divergence), esthetics, function, and periodontics. Replacement of congenitally missing maxillary lateral incisors, the second most commonly missing teeth, can involve (1) canine replacement, (2) tooth-supported restoration, and (3) implants. This paper contrary to the opinion of other authors, favors replacement of the congenitally missing lateral incisors in one of several ways, versus orthodontic space closure.     

Use of osseointegrated implants in adult orthodontic treatment: a clinical report

This article describes the complex dental treatment of an adult patient with multiple missing teeth, mild periodontitis, and a malocclusion. Titanium implants were placed in the posterior mandibular edentulous segments and became osseointegrated. The placement of the mandibular implants was originally designed for orthodontic anchorage. The mandibular implants would subsequently be used for implant-retained crowns on completion of orthodontic treatment. After a 4-month healing period, an impression was made of the implant hexes and a master cast was formed. Two-piece temporary healing abutments were placed on the implants and used to retain orthodontic brackets. The orthodontist retracted the mandibular anterior teeth using the posterior implants for anchorage. The abutment screws of the 2-piece temporary healing abutments were tightened to 20 N-cm at the insertion appointment and did not need to be tightened again during the course of orthodontic therapy. Standard orthodontic brackets were cemented to the 2-piece temporary healing abutments. Orthodontic treatment was accomplished uneventfully. Prosthodontic treatment was completed using the osseointegrated implants to replace the missing teeth. The methods described in this clinical report present clinicians with additional choices in the treatment of complex dental disease using osseointegrated dental implants.     

Multidisciplinary treatment approach with one piece implants for congenitally missing maxillary lateral incisors: a case report

Congenitally missing lateral incisors are a common clinical occurrence. Dental Implants have become a primary treatment option for replacement of these teeth. Many times in prosthodontic treatment planning a multidisciplinary approach is needed for a comprehensive out come. Prosthodontic treatment planning is needed prior to the patient's consultation and following treatment acceptance; the prosthodontist may need to coordinate treatment needs with other specialists, including an orthodontist and an implant surgeon. This article describes multidisciplinary management of a case presenting with spaced maxillary anteriors due to the congenitally missing lateral incisors. Treatment consisted of initial orthodontic space management to obtain adequate space for missing lateral incisors. Single piece, narrow diameter implants were placed in edentulous spaces on both sides. Aesthetic crown lengthening procedure was performed with all anterior teeth along with tissues surrounding the implants. Metal-ceramic crowns were given as definitive restorations, resulting into an acceptable aesthetic outcome.

Aesthetic evaluation in subjects treated due to congenitally missing maxillary laterals. A comparison of perception in patients, parents and dentists

The treatment of the congenitally missing maxillary lateral incisor is a challenge to the dental profession. The demand for optimal orthodontic and prosthetic treatment is high because the condition has an impact on facial aesthetic. The aims of the present study were to determine how different outcome of treatment were perceived by professionals and laypeople and to identify situations that caused dissatisfaction or satisfaction after space closure or tooth replacement. A panel of four groups (patients with missing laterals, parents to these subjects, patients with other malocclusion and general dental practitioners) were included. Sixteen cases with uni- or bilateral missing maxillary lateral incisors, treated with space closure or with prosthetic replacements were presented photographically to the panel. The prosthetic replacements included resin-bonded bridges, porcelain bonded to gold bridges and implants. The panel was asked to rate the overall appearance of the mouth, to rank up to three disturbing features and to rank the most important treatment goals in case of treatment need. An obvious difference between the panel groups was found. The general practitioners were less critical than laypeople in rating the overall appearance. Amongst dentists the tooth colour, the tooth shape and asymmetry were the most disturbing factors whilst laypeople were disturbed by colour, spacing and tooth shape. Half of the dentists did not find any treatment need whilst the corresponding figure amongst laypeople was 19 per cent.When a treatment need was confirmed the most common treatment goals amongst dentists were to change the colour or the shape of the teeth. The laypeople wanted to change the colour, the space condition or the shape of the teeth. The study has shown that professionals and laypeople are of different opinion when rating treatment outcome in cases with missing maxillary laterals. Careful planning to achieve optimal aesthetics should be performed.
