New materials and adhesion techniques enable minimally invasive prostheses for replacing missing anterior teeth. Resin-bonded fixed dental prostheses (RBFDPs) offer a viable alternative to implants when case selection and adhesive techniques are optimized.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Minimally Invasive Dentistry
Background:
- Advancements in dental materials and adhesion technologies are crucial for modern restorative treatments.
- Replacing missing anterior teeth presents unique challenges, particularly in younger patients or those with specific anatomical limitations.
- Traditional treatment options may be invasive or unsuitable for all patients.
Observation:
- Case Report 1: A 13-year-old female with a missing mandibular incisor received a resin-bonded one-wing lithium disilicate bridge due to age restrictions and inadequate space for implants.
- Case Report 2: An adult female with an impacted maxillary canine utilized a two-abutment bridge with minimal tooth preparation as an alternative to implants or conventional bridges.
Findings:
- Lithium disilicate and zirconia frameworks are suitable for fabricating minimally invasive prostheses, with material choice dependent on occlusal demands.
- The described techniques for RBFDPs, including lingual wings and retention grooves, demonstrate successful tooth replacement with minimal tooth structure removal.
Implications:
- Minimally invasive prostheses using advanced materials and adhesion techniques provide esthetic solutions for missing anterior teeth.
- Proper case selection and meticulous adhesive protocols are crucial for ensuring the long-term success and longevity of resin-bonded fixed dental prostheses.
