In developing countries like India, accident falls are the main cause of dental trauma and anterior teeth are frequently affected10.The treatment options are decided by the position of the fracture line, length of the remaining root segment and the presence or absence of a coronal segment. The chances of healing with calcified tissue is poorest in cervical-third fractures.1,11 If the fracture line extends below the level of the alveolar bone crest and the apical root segment has sufficient length, the treatment alternatives are crown lengthening, orthodontic extrusion, reattachment, post crown and extraction.
Crown lengthening is performed if the fracture line is not more than 1–2 mm below the alveolar bone crest. This

The bonding of the fractured tooth fragment provides a more resistant restoration to staining, abrasion than composite reconstruction, hence implicating positive psychological, emotional and social response from child as well as parents.
Composite resins are proved to have an irritating effect on periodontal tissues especially fibroblast17 , White Mineral Trioxide Aggregate was used in the present case to seal the fracture line enabling lesser possibility of leakage of dual cure composite across the fracture line. Even enzyme-linked immunosorbent assay (ELISA) has evidently demonstrated the stimulatory effect of Mineral Trioxide Aggregate on the production of bone morphogenetic protein (BMP-2) and TGF-1 by fibroblasts of human periodontium18 The present case report concluded that composite reinforced fiber post used with white Mineral Trioxide Aggregate for reattachment of mobile coronal segment was observed successful. The success of the treatment was again evaluated after one year which reveals the coronal portion in position with good esthetics. The radiological signs of periodontal health and
fill cavities, close gaps between your teeth and repair worn down edges of your teeth. Dentists are the ones who do the direct composite bonding which means that the procedure is usually done in one dental visit.
We often place dental crowns at J. Wesley Anderson, Jr., DDS whenever a patient has a tooth that is damaged to the point where it is no longer functional. The damages a tooth can have include cracks, chips, and decay as well as teeth that are worn down. A dental crown is essentially a cap for teeth that have these types of damages. It is made from porcelain and will be bonded over the top of your damaged tooth. When the crown is placed, it will give a tooth that has lost its function and appearance both the look and function of a healthy natural tooth.
Dental crowns. Broken, cracked, or decayed tooth? We can repair the structural integrity of your tooth as well as restore your ability to chew comfortably.
A bridge is considered radical treatment as adjacent tooth structure must be drastically reduced in this process. The bridge has been regarded as the standard of care for some time in the replacement of single and multiple missing teeth. However, in order to obtain optimal functional and aesthetic results for full-veneer bridges, a significant reduction in the amount of tooth structure is necessary, occasionally predisposing to endodontic, periodontal, and structural complications. The abutment teeth often become carious and thus have an increased rate of those individuals needing a root canal procedure. If one of the abutment teeth are lost a longer span bridge would be required. The implant procedure is more conservative and has a better prognosis. Implants have a high rate of success, do not require procedures on adjacent teeth and are not susceptible to caries.
Along with fractography and fractographic analysis of different types of instrument failure, with prevention and management of endodontic instrument fracture. My research strives to combine studies of basic biomaterial science questions with research on clinical applications. I must mention that this was only possible with the help of the UBC graduate endodontic team.
The cantilever bridge consists of an artificial tooth that is fused to two crowns on one side of the gap. The Maryland bonded bridge utilizes plastic teeth and gums and metal wire. The metal support is bonded to the existing teeth to provide extra support for the artificial teeth and gums, which are in turn fused to the metal wire. Implant-supported bridges are anchored into the mouth using — you guessed it — dental implants.
During the second phase, a device specifically sized for each child is also worn at night. It works to gently guide the incoming permanent teeth into the appropriate places, correct jaw relations, and expand the arches to make room for the larger incoming adult teeth. This helps to eliminate and prevent any improper dentition. This device is worn for only about two to five months before the final phase of treatment begins.
The treatment is based on the bases that diagnosing and treating cases of malocclusions at an early, discovery stage can go a long way to stem the problem. Today’s interceptive orthodontics treatment has done a lot to phase out permanent removal of teeth to correct the bite and late orthodontic treatment which traditionally began at around age 12 to 14. The treatment also reduces treatment time, creates and preserves space for the un-erupted teeth and creates a facial symmetry through fine jaw bone resetting. Children who undergo this phased treatment are often treated at age between 7 and 11 to take advantage of the continued teeth growth. The treatment at this age is much easier because the patient’s are much more receptive to the treatment thus ensuring better end
At your second appointment, we will remove the temporary crown, adjust the permanent crown as needed and give you an opportunity to confirm that it meets your expectations for comfort and appearance. Once we firmly cement the crown in place, you should expect to see a beautiful, natural-looking
The human tooth was observed under a Wild M32 Heerburg with transmitted light and magnification of 12X. The tooth, seen in Figure 3, was perceived to have an enamel on the surface and dentine observed in the hole. The enamel is the hard, white, outer layer of the crown, and protects the tooth. The dentine is the bulk of the tooth and surrounds the pulp. Biomaterials in used in human teeth to produce dental adhesives to bond the enamel and
The first procedure I observed was a placement of a porcelain-fused-to-metal (PFM) crown. The patient was in need of a crown due to fracturing tooth number 15. The procedure did not include anesthesia based on the patient’s preference. A
Although two recent meta-analysis have been published on this topic(38,39), they did not assess the entire spectrum of regenerative periodontal therapy techniques. Furthermore, none of these reviews meta-analyzed the safety profile of such procedures and only one admitted comparisons between different types of interventions.(38) Thus, a new systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the efficacy and safety of all possible regenerative techniques may add further information.
Based on the principle of Melcher (1976), GTR can be considered as a therapeutic resource that facilitates the repair of bone and periodontal defects, furcation lesions and gingival recessions, regenerating tooth support tissues, through the use of barrier materials such as membranes, that exclude the gingival epithelium from the root surface and provide allow spaces held by the barrier membranes (BM) to be filled by desired tissue (bone). (2, 3) By selecting the type of cells that will repopulate the wound, we allow the cells of the periodontal ligament to regenerate the lost tissues, inhibiting the early migration of the epithelial cells. (4-6) Despite the use of biomaterials to support membranes seems to improve the results, there still are many problems
However, a poor re-establishment of the original bone tissue after reabsorption was in various studies reported.2,6 In order to increase the bone restauration after absorption of biocomposite suture anchors, a third generation of anchors, containing β-tricalcium phosphate (TCP) and hydroxyapatite (HA), was recently developed.5,12 Which impact the addition of those osteoconductive materials on the osseous reaction have, is still unclear, and is currently being controversially discussed.9,16
The replacement of a single tooth lost due to dental caries or trauma can be challenging for a clinician. Traditionally several options are indicated in order to restore the edentulous space including implant/crown, fixed partial dentures (FPD) or removable partial denture (RPD). However economic factors, occlusal disturbances, lack of adequate bone support or excessive removal of healthy dental structure are some of the limiting factors in the traditional treatment modalities.
