Richmond crown; Post and core; Over jet; Overbite
Restoration of severely fractured/ decayed teeth requires crown restoration after endodontic therapy which is often major requisite in conservative dentistry. If there is steep incisal guidance and very less overjet then restoration of such crown is not possible with routine post and core followed by crown restoration because of very less incisal clearance. Richmond crown is advisable in such cases as it is single-unit post retained crown with porcelain facing design. Two cases have been discussed here with Richmond crown treatment modality over 2-3 years successful follow-up.
Restoration of endodontically treated teeth has always been challenge in dentistry. Grossly carious crowns, severe fracture of teeth involving more than two-third of crown structure requires additional retention from root canal for crown restoration especially after root canal therapy. In such cases post and core treatment modality has been advised. If such cases became complicated with deep bite and minimum overjet then it will be very difficult to place a prosthetic crown. Richmond crown can be placed in such situation as it does not require cemental interface between post- core and crown. This can also be advised in deep-bite cases involving minimum overjet with severely destructed tooth structure.
Richmond crown is a single-piece, post-retained crown with a porcelain facing designed to function as bridge retainer. Richmond crown is not a post and core system but it is customized castable post and crown system as both are single unit and casted together. It is easy to make cast metal restoration with aid of posts for long term retention .
Here, we have discussed two case reports one with fractured upper left central incisor involving Elli’s type III fracture complicating severe deep bite and very minimum overjet. Other case was having repeatedly dislodged crown in relation to upper left lateral incisor with minimum amount of tooth structure remaining. In both the cases crown was restored with Richmond crown treatment modality. We perceived successful follow-up for 2 years and 3 years respectively.
Case Report 1
25 years old male healthy patient reported with the chief complaint of fracture of upper left central incisor (Figure 1). Patient was conscious, cooperative and well-oriented with time, space and environment. He met with an accident and fell down on floor with the face downward. He noticed that his upper anterior tooth was fractured and blood oozing from the tooth. He tried to stop bleeding with handkerchief and immediately rushed to local physician. Physician put gauze in between teeth to stop bleeding and administered painkiller injection followed he asked patient to visit dentist.
