Abstract

The replacement of congenitally missing maxillary lateral incisors can be a challenge from both a prosthetic and surgical perspective. Fixed prosthodontic and removable prostheses, resin bonded retainers, orthodontic movement of maxillary canine to the lateral incisor site and single tooth implants represent the available treatment modalities to replace congenitally missing teeth. This case report demonstrates the team approach in prosthetic and surgical considerations and techniques for managing the lack of lateral incisors. Critical to achieving predictable esthetics and function for congenitally missing maxillary lateral incisors is the close communication between the prosthetic and the surgical team members.

Summary

Replacement of maxillary lateral incisors with congenital absence may be a challenge both prosthetically and surgically. Removable dentures, fixed prostheses, r-resin, orthodontic treatment of upper canines at the lateral incisor site and dental implants represent treatment modalities available for replacement of congenitally missing teeth This clinical case demonstrates the multidisciplinary prosthetic and surgical approach to treat the absence of lateral incisors. The close collaboration between the prosthesis and the members of the surgical team is essential for the aesthetic and functional success of agenesis of lateral incisors.

Introduction

Choosing and achieving a predictable esthetic and functional result for replacing congenitally missing maxillary lateral incisors from orthodontic, prosthetic, and surgical implant perspectives has been explored clinically [1]. The successful use of dental implants to replace missing teeth has been one of the most popular, exciting and evolving areas of clinical dentistry [1]. The ideal treatment option is dental implant. An interdisciplinary team approach is therefore recommended as the treatment is becoming more complex for the dental practitioner. An Interdisciplinary approach is required and involve a prosthetic and orthodontic treatment and following consultations with a periodontist or an oral surgeon and the implant modality treatment will be selected [2,3]. Astra Tech dental implant is a versatile system in such any restorative requirement can be addressed [4], The orthodontist must understand the critical parameters of aligning the roots and consultation with the periodontist who will surgically place the dental implants is critical [5,6]. The Angle Society of Europe addressed controversies relating to the management of the missing lateral incisors. The consensus was that the care of patients with congenitally missing lateral incisors is best achieved through a multi-disciplinary approach [7]. Implants do not require preparation of natural teeth and therefore can be considered the most conservative approach and their long-term success rates of implants have made them an obvious restorative choice.

Case Report

A 21 year old female was refereed from the orthodontic division, King Saud University college of Dentistry for management of missing laterals (Figure 1A-1C). After orthodontic treatment was finalized, the orthodontic brackets were removed and a removable appliance was used to replace the missing maxillary lateral incisors.

Implant Placement (Figure 2-11) Ridge evaluation and mapping was done under local anesthesia to evaluate bone width and was found to be adequate to accommodate an Osseospeed S 3.0mm wide, 15 mm length Astra Tech except in the apical area where the width was narrower therefore leading to some bone exposure. The left lateral was treated identically with an Osseospeed S 3.0mm wide, 15 mm length Astra Tech Company.

Discussion and Conclusion

The Absence of the maxillary lateral incisors in young patients creates an aesthetic problem which can be managed in many ways. The clinical condition requires a multidisciplinary approach with careful treatment planning and a consideration of the options and outcomes following either space closure or prosthetic replacement [8]. The reason is that dental Implant treatment planning in the case of congenitally missing maxillary lateral incisors depends on space requirements, occlusion and the condition of the neighboring teeth [3]. The ideal time for placement of fixed prosthesis iswhen the growth of the mandible maxilla and alveolus is complete. If the dental implant restored with a zircnonia such as the case presented in this paper is placed earlier before the growth is complete, the surrounding alveolar bone may continue to develop vertically and adjacent teeth may continue to erupt. It will lead to a disharmony between the gingival margin of the prosthesis and the natural therefore submerging the final prosthesis creating an esthetic and functional problem [9] It is the multidisciplinary approach that lead to the esthetic and functional success of this clinical case, Taking advantage of the synergy of the working team to maximize each clinician’s skill will contribute to the best clinical result for these young patients. This approach when well planned will have high predictability and acceptance by the patient [10,11].
