“…26,34,35 Further studies have found failure rates to be reduced when cantilever designs are used in preference to fixed/fixed designs. 36,37 Although all this evidence suggests that the RBB is an acceptable form of treatment, there is little evidence about the survival and clinical performance of RBBs when provided specifically for post-orthodontic hypodontia patients, and in particular the survival of RBBs replacing the commonly missing maxillary lateral incisor.…”

Objective To analyse the clinical performance and factors influencing the survival of resin-bonded bridgework provided for hypodontia patients with missing maxillary lateral incisors, following orthodontic treatment to open, maintain or redistribute the missing tooth space. Design A retrospective analysis of patients treated at a single centre using case notes with all patients invited for review to corroborate findings. Setting Departments of Orthodontics, Child Dental Health and Restorative Dentistry, Newcastle upon Tyne Dental Hospital and School. Subjects and methods Between 1989Between -2000 suitable hypodontia patients were identified of whom 45 had complete records. For these patients 73 resin-bonded bridges (RBBs) were provided. Following invitation, 24 patients attended for a review appointment. The survival of the RBBs, grade of operator providing treatment, duration of postorthodontic retention, the influence of design, presence of pontic contact in static and dynamic excursions, and the effect of habits were assessed. Life table, Kaplan-Meier and Cox regression analysis were carried out for the 73 RBBs with complete records. A separate analysis of the RBBs provided for patients who attended for the invited review did not show a higher failure rate than those patients who did not attend. Therefore both sets of data were combined. Results Of the 73 RBBs provided, 30 had debonded on at least one occasion (41.1%), six of these debonds were due to trauma (20%). The mean survival time of all the restorations was 59.3 months, with a median survival time of 59 months. Senior members of staff (Consultant, Senior Lecturer or Specialist Trainee) provided most restorations (n = 39) and achieved the highest mean survival of 72.6 months and median

“…No orthodontic treatment was realized due to the fact that the patient refused to wear brackets. Finally an adhesive cantilever bridge 9 was seated in order to replace the missing upper left lateral incisor. Having then reestablished function and esthetics, as well as having solved the problem of sensitivity, the patient was kept with these restorations and under recall every 4 months up to the point of complete soft and hard tissue maturation.…”

SUMMARY Objective The aim of this study was to present a case report of a patient affected by amelogenesis imperfecta showing a possible minimal and conservative adhesive treatment approach. Clinical Procedure A treatment philosophy of amelogenesis imperfecta is illustrated by means of a case report of a 14-year-old boy who consulted us for a full mouth rehabilitation. Discussion This clinical report describes step by step how to manage a case of amelogenesis imperfecta from childhood over time. Significance This kind of minimally invasive, progressive approach allows the conservation of maximum tooth substance together with an acceptable esthetic outcome.

“…It has been reported that single abutment, single pontic, cantilever, resin bonded bridges have several advantages over multi-abutment resin bonded bridge designs 16 and that cantilevers had a greater median survival than all other designs. 17 De-bond rates of 20%, 16 21%, 18 17% 19 and 32% 15 have been reported. It has been proposed that the Rochette retainer design is more prone to debonding because of the relatively small retentive area per retainer, but the facility for easier removal, cleaning and rebonding is recognised.…”

A retrospective clinical audit of the role and survival of 69 Rochette bridges used as immediate provisional restorations for single tooth, implant-retained crowns was carried out over the period between February 1991 and May 2001. In each case the extracted tooth was immediately temporised using a Rochette bridge with a single wing and pontic and cemented to the abutment tooth without any tooth preparation (Phase I). This bridge was removed at the time of implant placement and recemented (Phase II). At the implant exposure stage the bridge was removed and discarded. In Phase I, 15.9% of the bridges required recementation and 27.5% of the bridges required recementations in phase 2; 7.2% of the bridges required recementations in both phases. An 80% probability of survival was noted after an interval of 200 days for phase I and a 78% probability of survival over the same time interval was observed for Phase II. A significant debond rate was observed when the retainer was a canine in comparison to the other bridges in Phase I. In Phase I the spring cantilever debond rate was significantly higher than that observed on the other bridges. More debondings were observed in males (25.8%) compared with females (7.9%) in phase I. More debondings were noted in the maxilla than in the mandible in Phase II. The performance characteristics of the metal acrylic Rochette bridge observed in this report supports the conclusion that this type of restoration is an effective means of immediate temporisation for patients undergoing single tooth implant retained restorations.
