Abstract Aim The purpose of this case report is to present the esthetic and functional rehabilitation of the teeth in a 20-year-old patient with amelogenesis imperfecta (AI), facial asymmetry due to functional mandibular shift, and unilateral posterior crossbite. Background AI is a group of hereditary defects of enamel unassociated with any other generalized defects. AI results in poor development or the complete absence of the enamel of the teeth caused by improper differentiation of ameloblasts. Case Description This report describes the diagnosis and treatment of a young female patient with AI and facial asymmetry using a combined orthodontic-prosthodontic approach. Initially, the posterior crossbite, mandibular shift, and facial asymmetry were treated orthodontically. Later, metal-ceramic crowns for posterior teeth and allceramic crowns for anterior teeth were fabricated for final restorations. Summary Coordinated orthodontic and prosthodontic treatment, with careful consideration of patient expectations and requests, were critical for a successful outcome and patient satisfaction. Clinical Significance The complexity of the management of patients with AI supports the suggestion that the dental profession should have appropriate methods for the rehabilitation of rare dental disorders.

Abstract Aim The purpose of this case report is to present the esthetic and functional rehabilitation of the teeth in a 22-year-old patient with Amelogenesis imperfecta (AI). Background AI is a group of hereditary defects of enamel, unassociated with any other generalized defects. It is a rare developmental abnormality of the enamel, with a variable occurence of approximately 1:4000 to 1:14000 in Western populations. Al results in poor development or complete absence of the enamel of the teeth caused by improper differentiation of the ameloblasts. Report This report describes the diagnosis and treatment of a young male patient with AI and missing molar teeth using contemporary restorative strategies. Initially, the tooth surfaces were treated with a professional cleaning along with conservative restorative treatment. Later, metal-ceramic crowns for posterior teeth and fullceramic crowns for anterior teeth were utilized for final restorations. Summary The complexity of the management of patients with AI supports the suggestion the dental profession should have appropriate methods for the rehabilitation of rare dental disorders. The treatment of patients with AI should start with early diagnosis and intervention to prevent later restorative problems. Citation Gokce K, Canpolat C, Ozel E.

Case Report. An 8-year-old girl with amelogenesis imperfecta (AI) reported unsatisfactory aesthetics, difficulty in mastication, and dental hypersensitivity. The intraoral examination observed mixed dentition, malocclusion in anteroposterior relationships, anterior open bite, and dental asymmetry. A hypoplastic form of AI was diagnosed in the permanent dentition. A multidisciplinary planning was performed and divided into preventive, orthopedic, and rehabilitation stages. Initially, preventive treatment was implemented, with fluoride varnish applications, in order to protect the fragile enamel and reduce the dental sensitivity. In the second stage, the patient received an interceptive orthopedic treatment to improve cross-relationship of the arches during six months. Finally, the rehabilitation treatment was executed to establish the vertical dimension. In the posterior teeth, indirect composite resin crowns were performed with minimally invasive dental preparation. Direct composite resin restorations were used to improve the appearance of anterior teeth.Follow-Up. The follow-up was carried out after 3, 6, 12, and 18 months. After 18 months of follow-up, The restoration of integrity, oral hygiene, and patient satisfaction were observed .Conclusion. Successful reduction of the dental hypersensitivity and improvement of the aesthetic and functional aspects as well as quality of life were observed.

Amelogenesis imperfecta (AI) has been defined as a group of hereditary enamel defects. It can be characterized by enamel hypoplasia, hypomaturation, or hypocalcification of the teeth. AI may be associated with some other dental and skeletal developmental defects. Restoration for patients with this condition should be oriented toward the functional and esthetic rehabilitation. This clinical report describes the oral rehabilitation of a young patient diagnosed with the hypoplastic type of AI in posterior teeth and hypomatured type of AI in anterior teeth.

Treatment of severe occlusal cant requires a combination of fixed orthodontic treatment with orthognathic surgery. This case report was aimed to describe the combined fixed orthodontic treatment of Le Fort 1 in maxillary occlusal cant of class III dentoskeletal malocclusion with facial asymmetry. Case report: A female patient aged 17 years seven months came to the private clinic, complained of oblique maxillary teeth, and the right posterior was unable to masticate comfortably. The patient wants to be treated for her teeth and jaw. Extraoral examination revealed facial asymmetry, sunken profile and slightly protruding chin. The intraoral examination resulted in the maxillary median line that shifted to the left, mandible shifted to the right, anterior crossbite, unilateral posterior crossbite, and retrusion of maxillary and mandibular anterior teeth. The lateral cephalometric analysis resulted in class III dentoskeletal malocclusion. The diagnosis was class III dentoskeletal malocclusion with maxillary occlusal cant, facial asymmetry, anterior crossbite, and posterior unilateral crossbite. The treatment plan was fixed orthodontic treatment combined with Le Fort orthognathic surgery. The treatment was carried out in 4 stages: decompensated orthodontic treatment, maxillary orthodontic treatment, post-orthognathic surgery orthodontic treatment, debonding, and retainer placement. Conclusion: Class III skeletal malocclusion with maxillary occlusal cant, facial asymmetry, anterior crossbite, and the unilateral posterior crossbite was successfully treated with a fixed orthodontic appliance and Le Fort 1 orthognathic surgery. The dental and skeletal relations were achieved for class I, the interdigitation of the maxillary and mandibular teeth was locked, the masticatory function was corrected, and the patient was very satisfied with her facial aesthetics.Keywords: Class III skeletal malocclusion, facial asymmetry, maxillary cant, anterior crossbite, unilateral posterior crossbite, orthognathic surgery.

Abstract Objective To compare the accuracy of complete-arch scans and quadrant scans obtained using a direct chairside intraoral scanner. Material and methods Intraoral scans were obtained from 20 adults without missing teeth except for the third molar. Maxillary and mandibular complete-arch scans were carried out, and 4 quadrant scans for each arch were performed to obtain right posterior, right anterior, left anterior, and left posterior quadrant scans. Complete-arch scans and quadrant scans were compared with corresponding model scans using best-fit surface-based registration. Shell/shell deviations were computed for complete-arch scans and quadrant scans and compared between the complete-arch scans and each quadrant scans. In addition, shell/shell deviations were calculated also for each individual tooth in complete-arch scans to evaluate factors which influence the accuracy of intraoral scans. Results Complete-arch scans showed relatively greater errors (0.09 ~ 0.10 mm) when compared to quadrant scans (0.05 ~ 0.06 mm). The errors were greater in the maxillary scans than in the mandibular scans. The evaluation of errors for each tooth showed that the errors were greater in posterior teeth than in anterior teeth. Comparing the right and left errors, the right side posterior teeth showed a more substantial variance than the left side in the mandibular scans. Conclusion The scanning accuracy has a difference between complete-arch scanning and quadrant scanning, particularly in the posterior teeth. Careful consideration is needed to avoid scanning inaccuracy for maxillary or mandibular complete-arch, particularly in the posterior area because a complete-arch scan might have potential error than a quadrant scan.

Long Term Prognosis

ABSTRACT All of us as clinicians at one time or another have to attend to dental emergencies involving severly fractured or even lost or avulsed anterior teeth. Treating such cases is often difficult and there is always a time factor involved. Loss of anterior teeth can affect a patient psychologically and socially. This can be minimised by an immediate replacement or replantation of the lost or avulsed teeth. Definitive treatment planning and consultation with specialists is seldom possible at the time of emergency treatment. Replantation of the avulsed tooth can restore esthetic appearance and occlusal function shortly after the injury. This article describes the management of a young female with an avulsed maxillary permanent incisor that had been air-dried for about 72 hours. The replanted incisor retained its esthetic appearance and functionality 8 months after replantation, yet the long-term prognosis remains questionable.

AbstractWe report the frequencies of linear enamel hypoplasia (LEH) and, specifically, pitting enamel hypoplasia (PEH) defects in the teeth of Paranthropus robustus, for comparison with four other South African hominin species and three extant nonhuman primate species. Unlike LEH, the lesser known PEH is characterized by multiple circular depression defects across a tooth crown and is often difficult to interpret in terms of developmental timing and etiology. Teeth in all samples were examined macroscopically with type, position and number of defects recorded. Frequencies of teeth with LEH vary among hominin species, but the differences in PEH are considerable. That is, P. robustus has much higher rates of pitting defects, with 47% of deciduous teeth and 14% of permanent teeth affected, relative to 6.7% and 4.3%, respectively, for all other hominin teeth combined; none of the extant primate samples evidence comparable rates. The defects on P. robustus molars are unlike those in other species, with entire crowns often covered in small circular depressions. The PEH is most consistent with modern human examples of amelogenesis imperfecta. Additionally, the defects are: 1) not found on anterior teeth, 2) uniform in shape and size, and 3) similar in appearance/severity on all molars. A possible reason for this form of PEH is as a side effect of selection on another phenotype that shares the same coding gene(s), i.e., a genetic origin. Recent research on the ENAM gene provides one such possibility. Paranthropus likely underwent rapid evolution in the ENAM loci, with changes in this gene contributing to larger posterior teeth and thicker enamel. This same gene is associated with amelogenesis imperfecta; therefore, pleiotropy effects, relating to high selection on this gene during Paranthropus evolution, could have yielded this unique condition.

ABSTRACT Amelogenesis imperfecta is a rare hereditary disorder that affects dental enamel and is often associated with an anterior open bite. Orthodontic treatment of a 16-year-old female patient with hypocalcified amelogenesis imperfecta and a 9-mm anterior open bite was presented. Radiographic examination revealed a steep mandibular plane angle, an increased lower face height, a Class II skeletal pattern, and a convex profile. Additionally, the patient had stainless steel crowns on all upper and lower posterior teeth and composite veneers on the upper anterior teeth. The patient was treated nonsurgically using a multiloop edgewise archwire (MEAW). MEAW mechanics allowed for successful correction of the anterior open bite, with significant reduction in the mandibular plane angle and improvement in the patient's profile. No fixed retainers were used, results remained stable 78 months after removal of orthodontic appliances. MEAW mechanics should be considered for patients with large anterior open bites, although this technique requires excellent patient compliance.

Extraction Treatment

ABSTRACTMany approaches for crowded mandibular anterior teeth are currently employed: distal movement of posterior teeth, lateral movement of canines, labial movement of incisors, interproximal enamel reduction, removal of premolars, removal of one or two incisors, and various combinations of the above. Selecting the best treatment is often difficult, and all guidelines do not apply to every case. Treatment by extraction of one single mandibular incisor is not popular in the orthodontic profession despite the apparent advantages of the extraction in the region of crowding. A case report is presented one mandibular incisor extraction treatment of a 16 year-old female with a Class I malocclusion that shows a significant mandibular arch length deficiency and mandibular tooth-size excess. In this case, the degree of mandibular anterior dental crowding, existing mandibular tooth-size excess, and the dental midline discrepancy were indicated the extraction of one mandibular incisor.
