“…The retainer designs are illustrated in Fig. 4 , as follows: Group I, a premolar lingual wing with an occlusal bar combined with a molar lingual wing with double rests (MDR); group II, a lingual wing with an occlusal bar for both abutments (OBB); group III, a premolar lingual wing with an occlusal bar combined with a molar dental band (MDB) and group IV (control), a lingual wing with a single rest adjacent to the edentulous space (SRB), which was considered a typical design in a recent study ( 23 ). Prior to embedding, two-layered wet medical tape was wrapped around the abutment root as an artificial periodontal membrane.…”

“…A typical choice for retainer design of posterior RBFPDs consists of two wraparound 180° lingual wings and two rests adjacent to the edentulous space ( 23 ). A number of previous studies and literature reviews ( 5 , 7 , 23 – 25 ) have introduced modified retainer designs, including an inlay retainer, a retainer with mesiodistal double rests on one abutment, C- or D-shaped retainers and dental bands designated O-shaped retainers. Nevertheless, there are no standard posterior porcelain-fused-to-metal (PFM) RBFPD designs currently available for clinical use.…”

The aim of this study was to investigate the adhesive property of palladium-silver alloy (Pd-Ag) and the simulated clinical performance of Pd-Ag porcelain-fused-to-metal (PFM), resin-bonded, fixed partial dentures (RBFPDs). A total of 40 Pd-Ag discs (diameter=5 mm) were prepared and divided into the following four groups (n=10): a) No sandblasting, used as a control; and b, 50 µm; c, 110 µm; and d, 250 µm aluminum oxide (Al2O3) particles, respectively. Another 50 discs were pre-sandblasted and divided into five groups (n=10) subjected to different treatments: e) Sandblasting, used as a control; f) silane; g) alloy primer; h) silica coating + silane and i) silica coating + alloy primer. All 90 discs were bonded to enamel with Panavia F 2.0 and then subjected to shear bond strength (SBS) testing. The fracture surfaces were examined by scanning electron microscopy. Next, 40 missing maxillary second premolar models were restored with one of the four following RBFPD designs (n=10): I) A premolar occlusal bar combined with molar double rests (MDR); II) both occlusal bars with a wing (OBB); III) a premolar occlusal bar combined with a molar dental band (MDB); and IV) two single rests adjacent to the edentulous space with a wing (SRB) used as a control. All specimens were aged with thermal cycling and mechanical loading. Subsequently, they were loaded until broken. The data were analyzed by one-way analysis of variance. Al2O3 (250 µm) abrasion provided the highest SBS (P<0.05). The alloy primer and silica + silane exhibited increased SBS. Furthermore, fracture analysis revealed that the failure mode varied among the different treatments. Whereas MDB exhibited the highest retention (P<0.05), that of OBB was greater than that of MDR (P<0.05), and the control exhibited the lowest retention. Abrasion with Al2O3 (250 µm) effectively increased the adhesive property of Pd-Ag. Additionally, treatment with the alloy primer and silica coating + silane was able to increase the adhesive property of abraded Pd-Ag. Under the present conditions, all three modified retainer types provided improved outcomes for Pd-Ag PFM RBFPDs compared with the control.

“…Regardless of whether the location is posterior or anterior, RBFPDs have been accepted as an alternative treatment to conventional fixed-partial-dentures (FPDs) when intact abutments are present and minimal intervention is desired [ 4 ]. The main advantage of RBFPDs in comparison to conventional FPDs preparations is that they are conservative to tooth structure.…”

Congenitally missing teeth and/or hypodontia is a prevalent dental anomaly. There are different treatment options available for these conditions such as space maintenance, restoring the space by resin-bonded-fixed-partial-dentures (RBFPDs), and dental implants. This study addresses the comprehensive treatments for congenitally missing tooth and diastema using interdisciplinary approaches. One patient was treated with small-diameter-implants and the other one was treated using an intraoral scanner to make digital impression and fabricating RBFPDs with CAD/CAM system. Both patients were completely satisfied.

“…In fact, it has been introduced since 1973 as a temporary procedure. This system was conceived by ROCHETT as a splinting system using retainers in a periodontally compromised incisor and it was limited to the mandibular anterior region 7 . Whereas, it has been proved by recent studies that, when it is used to replace a missing tooth it offers an acceptable survival rate which has been evaluated between 81.6% and 91.9% after 5 years 8 .…”

“…These treatments include many procedures such as surface abrasion, application of a tribochemical silica coating and the chlorosilane treatment 12 Currently allying the performance of bonding systems Zirconia based frameworks are resistant, enough, to provide viable conectors in double retainers bonded bridges. Moreover, it can also, solve the aesthetic problem caused by metal retainer in metal ceramic concept; which is a basic problem confronted by both clinician and patients 7 .…”

This article describes a case of rehabilitation of a missing lateral incisor using a Zirconia based resin bonded fixed partial denture. An 18 year old female patient with the agenesis of lateral incisor and a peg lateral incisor in the other side presented to prosthetic department .This aspect was compromising the self satisfaction of the patient. She desired a more attractive appearance. After a comprehensive examination, adjacent teeth to edentulous area were sound with a suitable height. Implant therapy was excluded. The treatment plan included a Zirconia based resin bonded bridge in the right side. The peg lateral incisor was reshaped using a provisional restoration until growth achievement and tissues maturation
