They define the mouth’s corner, are involved in the aesthetic smile, maintain occlusal stability, and design the shape of the dental arch. As the position of the impacted canines is amidst vital anatomical structures like the nasal cavity and sinuses in the maxilla and mental nerve in the mandible, a thorough radiographic evaluation to determine the position of the impacted canines is of utmost importance prior to any treatment planning. By using a radiographic image, a clinician can clearly identify its location. The present paper aimed to determine the prevalence, etiology, and clinical diagnosis of impacted maxillary canines in orthodontic patients.

Selecting the appropriate treatment option depends on many factors, such us the malocclusion, the anterior relationship, specific space requirements, bone volume, root proximity, the condition of the adjacent teeth, and esthetic prediction mainly when the canine must be reshaped.Resin bonded bridges were considered to be doomed owing to their very high decementation rate, have come alive once again because of newer resin based cements. This article will discuss the variety of treatment managements in case of space opening and treated with two 2-unit cantilevered resin-bonded fixed partial dentures supported by the cuspids. This conservative treatment plan was cost-effective without having any significant biological cost.

Conventional fixed partial dentures and implant-supported restorations may often be the treatment of choice. Fiber-reinforced composite (FRC) resins offer a conservative, fast, and cost-effective alternative for single and multiple teeth replacement and may prove to be a successful modality for aesthetic and functional replacement of missing teeth along with periodontally compromised abutments, which has always been a challenge for the dentist. The aim of the case report is to describe the clinical procedure in rehabilitation of edentulous space through fabrication of direct fiber-reinforced composite resin fixed partial denture with periodontal splinting of adjacent teeth.

The purpose of the present retrospective radiographic study was to provide data concerning the prevalence of non-syndromic hypodontia in patients reporting to the Center for Dentistry,Research & Aesthetics, Jatt, Almothalat, Israel. Material and Methods: Five hundred consecutive patients who met the inclusion criteria were selected from the records. The radiographic records included at least one clear adequate quality Orthopantomogram (OPG), which was supplemented when necessary by a periapical radiograph. Results: A prevalence of 2,6 percent hypodontia was seen in the sample. Conclusions: It was concluded that hypodontia is prevalent in Arabs population in Israel with a 2,6% incidence which is on the higher limit of the global range (1.6-9.6%). However further studies should be conducted on a larger nonorthodontic sample to determine accurately this incidence of hypodontia.

Since years, many modes of treatment options have been available such as removable temporary acrylic prosthesis or resinbonded bridges variety of therapeutic modalities, and from implants to conventional Maryland bridges. But the recent inception of fibre-reinforced composites (FRCs) in tooth replacement therapy has opened a new perspective in the field of restorative dentistry. Fibre-reinforced composites have been incorporated with better properties with flexural strength and fracture resistance. FRC bridges are easy, minimally invasive and reversible and a single visit procedures. It also lets other options viable for future, if need be. This paper presents a case of a missing mandibular left central incisor, which were replaced with acrylic tooth pontic using fibre-reinforced composite. .

Numerous efforts have been made to understandthe etiology of CL/P so as to predict its occurrence and to prevent it from occurringin the future. In the recent years, advances in genetics and molecular biology havebegun to reveal the basis of craniofacial development. Various genetic approaches,including genome-wide and candidate gene association studies as well as linkageanalysis, have been undertaken to identify aetiologic factors, but results have oftenbeen inconclusive or contradictory. These results may support the presence ofaetiologic heterogeneity among populations and the presence of multiple genesinvolved in the aetiology of CL/P. Despite these difficulties, several different geneshave been implicated in harbouring genes that contribute to the aetiology of CL/P. In conclusion, the genetic basis of CL/P is still controversial because of genetic complexity of clefting.

Black triangle will ruin the patients' smile and is not desirable. Composite resin used to close diastema should have adequate convexity from gingivo-incisal direction to avoid this problem. Various techniques have been introduced to close diastema, some of which are time-consuming or cannot provide proper contour. Case detail: This article describes a case in which diastema between two teeth was closed with direct composite resin with minimum amount of time. Although closing diastema with direct composite depends on operator skill in most part, this technique is probably less dependent on operator skill compared to other techniques. Conclusion: Closing diastema between anterior teeth with composite resin with direct technique is conservative and timesaving, and the presented technique which provides adequate contour can be carried out very easily by many dental practitioners

Among the missing one's, maxillary lateral incisor is more frequent causing esthetic and functional impairments in the affected individual. It might be associated with systemic problems, syndromic conditions or other oral anomalies. Management of missing lateral incisors involves a multidisciplinary approach for rehabilitation of impaired esthetics and function. Fiber-reinforced composite (FRC) resins offer a conservative, fast, and costeffective alternative for single and multiple teeth replacement and may prove to be a successful modality for aesthetic and functional replacement of congenitally missing teeth, which has always been a challenge for the dentist. The aim of the case report is to describe the clinical procedure in rehabilitation of edentulous space through fabrication of direct fiber-reinforced composite resin fixed partial denture with periodontal splinting of adjacent teeth.

Numerous animal experiments yielded evidence of rebuilt temporomandibular structures after mandibular protrusion. However, the mode and extent of structural and/or topographic changes of the disco-condylar relation after functional orthopaedic treatment is still an issue at stake. A problem exists in defining the physiologic (centric) position of the condyles and the proper disco-condylar relation which is tentatively determined by various methods particularly in MRI studies. Despite the high resolution provided, the results have to be interpreted with caution, as osseous resorption and apposition can not be assessed by visual evidence. In this article a prospective study is presented which proves the effectiveness of the "Wuerzburg concept", i.e. bionator plus extraoral traction and up-and-down elastics, and its impact on the temporomandibular joint. The underlying reactions are studied by means of MR images obtained from sucessfully treated patients.

However, while the consequences of cleft lips and palates can be severe and longlasting, these can be averted by medical intervention, especially if it is done as early as possible. This paper explores the various options for surgical, medical, dental, and speech and audiological management of cleft of the secondary palates in children with Apert's syndrome and the ways in which these interventions can help children with these particular birth defects.

This prospective study evaluates the outcome of forced orthodontic eruption of impacted canine teeth in both palatal and labial positions. Eighty-two impacted maxillary canines in 2200patients were included in the study and were observed for 2006 to 2013 ,in Center for Dentistry research and Aesthetics, Jatt/Israel after exposure. Following exposure by means of a palatal flap or an apically repositioned buccal flap, an orthodontic traction hook, with a Titanium Button with chain by Watted (Dentaurum) attached, was bonded to each impacted tooth using a light cured orthodontic resin cement. A periodontal dressing was placed over the surgical site for a period of time. All teeth were successfully erupted. Complications consisted of: failure of initial bond, at the time of surgery, which required rebonding; premature debonding at the time of pack removal and; debonding of b...

The clinical indicators of diagnosing this parafunction were the presence of dental wear/attrition and bruxofacets. The disorder appears more frequently in the younger population. The prevalence in children is between 14 to 20%. The present case report refers to a patient who reported to the Center For Dentistry,Research & Aesthetics, Jatt, Almothalath, Israel ,with the complain of Bruxism .A brief review is made of the literature concerning the etiology,clinical diagnosis and the therapeutic approach of the disease.
Corticotomy-assisted orthodontic treatment is an established and efficient orthodontic technique ... more Corticotomy-assisted orthodontic treatment is an established and efficient orthodontic technique that has recently been studied in a number of publications. Corticotomy facilitated orthodontics have been employed in various forms over speed up orthodontic treatment It involves selective alveolar decortication in the form of decortication lines and dots performed around the teeth that are to be moved. It is done to induce a state of increased tissue turnover and a transient osteopenia, which is followed by a faster rate of orthodontic tooth movement. This technique has several advantages, including faster tooth movement, shorter treatment time, safer expansion of constricted arches, enhanced post-orthodontic treatment stability and extended envelope of tooth movement. The aim of this article is to present a comprehensive review of the literature, including historical background, contemporary clinical techniques, indications, contraindications, complications and side effects.

There are some physiological and/or pathological conditions which result in excessive exposition of the gums. This causes a negative appearance and limits facial expression. Altered or delayed eruption is one of the main causes of gummy smile. This clinical report describes a gingivoplastic and Osteoplastic procedure for reduction of excessive gingival display.

Achievement and maintenance of implant stability are prerequisites for successful clinical Outcome. Therefore, measuring the implant stability is an important method for evaluating the success of an implant. The aim of this clinical study was to measure the implant stability quotient using a method called resonance frequency analysis of dental implants during the healing period. Material and methods: A number of 43 patients received 152 Shark AL-Technology implant system either in the maxillary or in the mandibular arch. Implant stability was measured with an Osstell Mentor device (Osstel, AB, Sweden) using the resonance frequency analysis at the time of implant placement, 0, 2, 4, 8 and 12 weeks post insertion. Results: The mean implant stability quotient for all implants placed was 72,18. The lowest value of the implant stability quotient was at 2 weeks post insertion measuring 60,78. Conclusions: In relation to the gender the implants placed in female patients showed a higher mean value of the implant stability quotient. In relation to the location within the dental arch the implants placed in the anterior areas had a higher implant stability quotient than the ones places in the posterior areas of the arch. If an implant is not stable at the time of installation, micromotion may occur during the healing period, thereby resulting in a thin fibrous layer at the bone-implant interface, an impediment to full osseointegration and a potential harbin ger of future implant failure [7] (Figure 1). Following the placement of an endosseous implant, primary mechanical implant stability is gradually replaced by biologic stability after some weeks post placement. After the initial placement of the implant, there will be a space between the implant surfaces and the bone, and blood clot formation results in the organization of early granulation tissue after four days [7,8]. This tissue will give rise to an osteocoating of the implant sur faces, which initiates the processes of bio logical stability. Thereafter, woven bone in opposition to the implant surface will remodel to form bone within the first 2-4
