Summary
Congenitally missing teeth (CMT) treatment requires a multidisciplinary approach. This case study details using implant-supported restorations (ISRs) and orthodontics to restore missing lateral incisors and enhance a patient
Area of Science:
- Dental Implantology
- Prosthodontics
- Orthodontics
- Esthetic Dentistry
Background:
- Congenitally missing teeth (CMT) present a complex treatment challenge requiring comprehensive management.
- Traditional treatment options like removable partial dentures (RPDs) may not offer long-term esthetic or functional satisfaction.
- A multidisciplinary approach integrating various dental specialties is often essential for optimal outcomes in CMT cases.
Purpose of the Study:
- To present a case of congenitally missing lateral incisors (CMT at sites 7 and 10) in an adult female patient.
- To illustrate the successful replacement of a long-standing removable partial denture (RPD) with implant-supported restorations (ISRs).
- To demonstrate the enhancement of smile esthetics through a combination of ISRs, lithium-disilicate crowns, and veneers.
Main Methods:
- The treatment plan involved the placement of implant-supported restorations (ISRs) at the edentulous sites.
- Custom zirconia abutments were fabricated to support lithium-disilicate crowns for the missing lateral incisors.
- Lithium-disilicate veneers were planned for adjacent teeth to achieve smile harmony.
- Limited fixed orthodontics were employed to create adequate space for the ISRs prior to implant placement.
Main Results:
- The case successfully utilized implant-supported restorations (ISRs) to replace congenitally missing lateral incisors.
- The combination of lithium-disilicate crowns on custom zirconia abutments and veneers provided enhanced esthetics.
- Orthodontic preparation was crucial for achieving sufficient space, facilitating the successful integration of ISRs.
Conclusions:
- A multidisciplinary treatment approach, including orthodontics and implant-supported restorations (ISRs), is highly effective for managing congenitally missing teeth (CMT).
- This case highlights the successful restoration of function and esthetics in an adult patient with missing lateral incisors.
- The use of advanced materials like lithium-disilicate and zirconia contributes to predictable and aesthetically pleasing outcomes in complex restorative cases.
