Intra-alveolar transverse crown & root fx. provokes many problems in treatment. Conventionally, extraction of the injured tooth and its prosthodontic restoration has been the treatment of choice. Though orthodontic extrusion could be an alternative treatment, there would be a situation it's inadequate to apply. Loss of natural tooth would be a psychological damage to the patient, of course. This report describes a replantation method of tooth in case of intra-alveolar transverse crown & root fracture. The fractured tooth was extracted, rotated, then replanted. Fixation and esthetic restoration was done. And then endodontic treatment was followed. Continuing follow-up of its function and endodontic status is required.

In case of gingival recession and alveolar bone defects due to tooth loss for a long period of time in a single tooth in the maxillary anterior region, it is not easy to obtain aesthetic results with a single implant prosthesis. For aesthetic restoration, it is important to preserve hard and soft tissues through alveolar bone augmentation as well as restore harmony with adjacent teeth and soft tissues by placing the implant in an ideal location. In this case, an implant was placed using guided bone regeneration and a connective tissue graft simultaneously with immediate implantation after extraction from the maxillary anterior region where only residual root was left for a long period of time.

Crown fractures are relatively common trauma to anterior teeth, and should be restored immediately in most cases. For those who suffer from unfortunate traumatic episode, the best treatment option should be minimally invasive approach. In the presence of fractured tooth fragment, reattachment procedure creates positive emotional response in the patient and simplifies the procedure and maintenance of the patient's original tooth anatomy and occlusion. Without fractured tooth fragment, next conservative option could be direct composite restoration which is based on minimal invasion concept. This article proposes simple and very conservative techniques that anyone can do in daily practice.

Objectives: Patients with excessive tooth wear should first be diagnosed for the etiology of the tooth wear. Causes of tooth wear include bruxism, clenching, and taking medications for systemic diseases. After identifying the cause of tooth attrition, the final prosthesis should be restored with an appropriate vertical dimension. Methods: A 79-year-old man with worn out teeth desired a whole dental treatment. He was on medications for high blood pressure and asthma. The treatment proceeded with a consultation with a medical doctor. The medications for asthma evoked multiple teeth wear and a loss of the vertical dimension. After recovery of 3 mm of vertical dimension, 2 months of evaluation was followed by an interim prosthesis. Results: The increased vertical dimension caused no problem in function and esthetics, and the final restoration was performed with a full monolithic zirconia crown. Group function, adequate anterior guidance, and the occlusal plane were determined. Conclusions: After the final restoration, the patient was both esthetically and functionally satisfied, and a night guard splint was delivered to prevent prosthesis fracture. The patient was informed about the potential tooth wear associated with asthma drugs and educated to visit the clinic regularly.

Successful treatment of a badly broken down tooth with pulpal disease depends not only on good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy is completed. The ideal treatment of endodontically treated teeth has been widely and controversially discussed. Endocrown is a restorative option for endodontically treated teeth. Endocrown design incorporates the core and short post into the crown as a single restoration. The preparation of endocrown consists of a circular equigingival butt-joint margin and central retention cavity of the entire pulp chamber instead of employing intraradicular posts. This design significantly increases the surface area of the preparation available for cementation. It is particularly useful in young patient teeth for long-term provisional restoration and in teeth with short clinical crowns. This technique represents a promising and conservative method for the treatment of endodontically treated teeth that require long-term protection and stability. Endocrown can be considered as a feasible alternative to full crowns or composite overlays for the restoration of non vital teeth.

The requirements for the successful treatment of all-ceramic restorations are not so different from the ones of conventional restorations. "The provisional restoration followed by an adequate tooth reduction" and "the accurately fitting prostheses with corresponding to final impression" can be the examples of them. Nevertheless, the one which all-ceramic restorations are distinguished from conventional restorations is the additional procedure of so called "bonding". In addition to the application of resin cement between "inner surface of restoration and outer surface of abutment", bonding technology can be also applied to the treatment process of "Post and Core" in particular if the abutments are non-vital teeth. Core build-up for all-ceramic crown is conducted with fiber post and tooth colored composite by considering the properties of the restorations transmitting light. I would like to share my clinical experience about "silica based ceramic and non silica based ceramic restoration.

With the increasing demand for esthetics and minimum intervention concept, people want to restore the fractured tooth with direct composite restoration. But even now, many dentists hesitate to do the direct resin restoration in the anterior region and shift the responsibility to dental technicians. This article describes each steps in restoring Class IV cavity. To obtain an esthetic result in anterior restoration, layering technique is mandatory and clinical tips suggested in this article would be useful.

For about half a century. dental implants made of titanium have developed as a method of restoration for the tooth loss. In these days. the titanium implants seem to be considered as the alternative for the conventional prosthodontics. But its hard to say that the titanium implants are superior to the treatments that preserve the natural tooth. As this is a general opinion among dentists. the implant will not be able to be the alternative for all the prosthetic treatments. Clinically, there are many causes for extracting tooth. The severe destruction of the tooth structure or periodontal diseases leads to inevitable tooth extraction. When the complete cure is doubtful because of narrow intraoral visibility and improper accessibility in approaching to the tooth and periodontal lesion, we. clinicians often inevitably extract tooth. Passive treatments like conventional restoration, curettage or surgical flap cant be the perfect treatments for the tooth that has subgingival root caries or severe periodontal diseases involved furcation. Many clinicians might have been forced to pull out the relatively healthy tooth by the difficulties of approaching to the lesions and poor prognosis. Though the intentional tooth replantation is performed sometimes. as it doesnt have enough scientific foundation. it has not been considered as a popular treatment method yet. I have been felt keenly the necessity of positive tooth preservation, so I have been attempting the treatment that has new concept. calling Natural Tooth Implantation (NTI) clinically. NTI differs from the tooth replantation in the goal for the treatment and biological healing process. Now. I confirm that NT! is a very positive and valid method of tooth preservation. Like you can get from the name. NTI is the dental implant procedure using natural teeth and similar to the healing process of the titanium implants in many aspects. I have been using biocompatible composite resin. DRM. with NTI and got affirmative clinical results from that. So I would like to introduce.roduce.

A fiber-reinforced composite (FRC) fixed prosthesis is an innovative alternative to a traditional metal restoration, as it is a conservative treatment method. This case report demonstrates a detailed procedure for restoring a missing anterior tooth with an FRC. A 44-year-old woman visited our department with an avulsed tooth that had fallen out on the previous day and was completely dry. This tooth was replanted, but it failed after one year. A semi-direct technique was used to fabricate a FRC fixed partial prosthesis for its replacement. The FRC framework and the pontic were fabricated using a duplicated cast model and nanofilled composite resin. Later on, interproximal contact, tooth shape, and shade were adjusted at chairside. This technique not only enables the clinician to replace a missing tooth immediately after extraction for minimizing esthetic problems, but it also decreases both tooth reduction and cost.

The restoration of endodontic tooth is always a challenge for the clinician, not only due to excessive loss of tooth structure but also invasion of the biological width due to large decayed lesions. In this paper, the 7 most common clinical scenarios in molars with class II lesions ever deeper were examined. This includes both the type of restoration (direct or indirect) and the management of the cavity margin, such as the need for deep margin elevation (DME) or crown lengthening. It is necessary to have the DME when the healthy tooth remnant is in the sulcus or at the epithelium level. For caries that reaches the connective tissue or the bone crest, crown lengthening is required. Endocrowns are a good treatment option in the endodontically treated tooth when the loss of structure is advanced.
