4. INTRODUCTION There are several treatment dilemmas where conventional fixed or removable prosthesis do not appear completely satisfactory. It should preserve tooth structure and should not limit the future treatment options in adulthood. However, treatment with RPD has a high “biological cost” with high caries incidence and periodontal breakdown of abutment teeth. 4

5. Fixed prosthesis also has a certain amount of failure rate due to insufficient crown length, also in young teeth that possess large pulp chambers tooth preparation becomes difficult. Therefore, a resin bonded fixed dental prosthesis is a suitable treatment option. Resin bonded or resin retained bridges are minimally invasive fixed dental prosthesis which rely on composite resin cements for retention. First described in 1970s, the resin bonded bridges have evolved significantly. 5

10. With improvements in the field of adhesive dentistry, resin-bonded bridgework has become a viable option for the long-term replacement of missing teeth. Functionally and biologically superior Preparations are confined to enamel Reduces the risk of devitalization High esthetic potential 10

11. 11 Ideal in defect free abutment Suitable for Young patient. Short span Favourable occlusion Teeth with large pulp horns where conventional bridge is difficult.

12. CONTRAINDICATIONS Abutment teeth with large carious lesions, extensive restorations, or severely abraded teeth. Abutment teeth where esthetics cannot be improved by bonding from the lingual surface. Cannot be used in areas of deep bite. 12

22. Etched Cast Resin Bonded FPDs (Maryland Bridge): 22

23. 23 Eventhough tooth preparation for Rochette bridge and Maryland bridge are similar, surface treatment makes the later prosthesis superior to rochette bridges. . Here mechanical retention is achieved by micro - porosities created on the tissue surface of retainers through the process of etching .

24. After etching, the wax is removed, and the framework is immersed in an 18% hydrochloric acid solution in an ultrasonic cleaner for 15 minutes to remove the black surface layer of the alloy formed as a result of etching. 24

28. The major problem with this technique is that it resulted in bulky wings, which are not periodontally acceptable and also incorporation in to posterior retainer is difficult because of their curvature. 28

35. Indications For the immediate restoration of esthetics following extraction or traumatic loss of an anterior tooth. Where metal display may compromise esthetics, e.g. where metal wings of traditional RBBs may cause grey ‘shine-through’ on thin anterior abutments. To maintain space in the developing dentition to simplify future orthodontic or esthetic restorative interventions. 35

71. Dandekeri SS, Dandekeri S. Single anterior tooth replacement by a cast lingual loop connector - a conservative approach. J Clin Diagn Res. 2014 A 19-year-old male reported with a missing upper right central incisor and requested an aesthetic replacement while maintaining his midline diastema. A loop connector resin-bonded FPD was planned using the left central and right lateral incisors as abutments. After diagnostic impressions, lingual tooth preparations and framework design were done. The framework with loop connectors was cast, tried in, and veneered with porcelain. Final cementation was performed with resin cement after confirming fit and aesthetics. The patient was satisfied with the result. 71

Pak J Med Sci. 2021 Case Report: A 24-year-old female with congenitally missing maxillary right lateral incisor (#12) received an FRC-supported FPD. After tooth shade selection and model preparation, a modified ridge lap pontic was fabricated with microhybrid composites and reinforced with glass FRC . Grooves were prepared on abutment teeth and pontic , surface treatments were done, and the FRC was bonded with flowable and microhybrid composites. Final finishing and occlusal adjustments were completed. Follow-up: At two years, the restoration showed good function and esthetics with only slight color change, and no fracture or debonding. 73

75. Conclusion Resin bonded fixed partial dentures provide a conservative, aesthetic, and cost-effective treatment option, especially for young patients and short anterior spans. With proper case selection, technique, and advances in bonding systems, they offer good longevity and preserve tooth structure compared to conventional bridges. 75
