Patients with considerable maxillomandibular anteroposterior discrepancies and maxillary hypoplasia require corrective treatment through orthognathic surgery. However, in the treatment of severe maxillary retrognathism, it is necessary to reconstruct areas of bone deficiency through grafting techniques in addition to maxillary advancement using only the Le Fort I osteotomy. Treatment in these patients is more challenging and requires high surgical predictability. Alloplastic materials often have been used for the reconstruction of poor bone contours...

BACKGROUND: Reverse headgear (a facial mask) is one of the most frequently used interceptive orthodontic devices in patients with Class III malocclusion. It is a simple device but may present some drawbacks related to pressure on the skin generated by the forehead and chin supports linked to the maxillary intraoral appliance by elastics. This can cause injury to the chin and lips. METHODS: Patients between 7 and 8 years of age were selected from the Unit of Pediatric Dentistry...

Introduction: India is home to many tribes which have an interesting and varied history of origins, customs and social practices. Oral health care in tribal areas is limited due to shortage of dental manpower, financial constraints and the lack of perceived need for dental care among tribal masses. Objective: To assess orthodontic treatment need among tribal children of Indore division, Central India. Methods: A cross-sectional house to house survey was carried out among 800 tribal children aged 5 to 15 years old in two major tribal districts of Indore division...

Severe malocclusion can contribute to several serious dental and physical conditions, such as digestive difficulties, periodontal disease, and severe tooth decay. Orthodontic treatment is mainly used to treat malocclusion. Forces in orthodontic tooth results in bone resorption on the pressure side and bone deposition on the tension side. Osteoblasts have been considered as the key component in bone regeneration on the tension side. However, the underlying mechanisms remain unclear. In this study, we focus on how mechanical stretch regulates the osteogenesis during orthodontic treatment...

The aim of the present study was to evaluate factors associated with sleep bruxism in five-year-old preschool children. A preschool-based cross-sectional study was conducted with 761 pairs of children and their parents/caregivers. Sleep bruxism was diagnosed using a questionnaire administered to the parents/caregivers, who also answered questionnaires addressing sociodemographic data and parent's/caregiver's sense of coherence. Clinical oral evaluations of the children to determine dental caries, traumatic dental injuries, malocclusion and tooth wear were performed by two researchers who had undergone a training exercise (interexaminer Kappa: 0...

Sagittal maxillary deficiency is frequently observed in patients with operated unilateral complete cleft of the lip and palate. Treatment for moderate to severe Class III malocclusion usually relies on LeFort I surgery for maxillary advancement after the end of growth. This case report describes bone-anchored maxillary protraction in a 10-year-old white boy with unilateral complete cleft of the lip and palate. His interarch relationship was diagnosed as GOSLON index 5 before treatment with a negative overjet of 3...

INTRODUCTION: The purpose of this study was to describe the skeletal and dentoalveolar changes in a group of growing skeletal Class III patients treated with hybrid rapid palatal expansion and facemask. METHODS: Twenty-eight growing patients with skeletal Class III malocclusion were treated using a rapid maxillary expander with hybrid anchorage according to the ALT-Ramec protocol (SKAR III; E.P.), followed by 4 months of facemask therapy. Palatal miniscrew placement was accomplished via digital planning and the construction of a high-precision, individualized surgical guide...

INTRODUCTION: Mandibular retrognathism is a type of malocclusion that refers to an abnormal posterior position of the mandible as a result of a developmental abnormality. From the literature, it is evident that the mandibular growth pattern is determined by the intramembranous ossification of the mandibular body and endochondral ossification of the condyle. Matrilin-1 is a cartilage extracellular matrix protein, and matrilin-1 gene (MATN1) polymorphisms have been found to be involved in dental malocclusions of humans...

INTRODUCTION: The objective of this study was to evaluate the effect of a new approach-bimaxillary miniplates-based skeletal anchorage-in the treatment of skeletal Class II malocclusion compared with untreated subjects. METHODS: The study (miniplates) group comprised 28 patients (14 boys, 14 girls) with skeletal Class II malocclusion due to mandibular retrusion, with a mean age of 11.83 years. After 0.017 × 0.025-in stainless steel archwires were placed in both arches, 4 miniplates were fixed bilaterally, 2 in the maxillary anterior areas and 2 in the mandibular posterior areas, and used for skeletal treatment with elastics...

INTRODUCTION: The aim of this study was to assess long-term changes and describe the trajectories of oral health-related quality of life (OHRQoL) in a cohort of cleft, surgery, and standard patients who received orthodontic treatment. METHODS: Standard (n = 16), cleft (n = 19), and orthognathic surgery (n = 22) patients completed the short-form of the Oral Health Impact Profile (OHIP-14) before treatment, immediately posttreatment, and approximately 5 years posttreatment...

Anterior crossbite is one of the most common forms of malocclusion in sagittal relationship of maxilla and mandible. If not corrected at the earliest, it will cause restriction of normal growth and development of both the jaws. The incidence of anterior crossbite is 4 to 5% in primary dentition. Self-correction may occur at the transient dentition or permanent dentition stage, but treating it should be the first priority. Using either removable or fixed appliances is recommended for the correction, but it depends on the patient cooperation, treatment duration, and parent approval...

INTRODUCTION: It has been suggested that alveolar corticotomies may accelerate tooth movement, broaden the scope of malocclusion types that can be treated orthodontically, decrease the need for extractions, and support long-term stability. Several techniques have been proposed, although the indications, ideal design and technical characteristics, potential complications, and objective clinician and patient satisfaction remain unclear. This systematic review aimed to provide scientific support to validate alveolar corticotomies as a reliable approach to accelerated orthodontics...

BACKGROUND: To assess the prevalence of malocclusion and orthodontic treatment need among adolescents using the dental health component (DHC) of the index of orthodontic treatment need (IOTN). METHODS: A descriptive cross-sectional study was conducted among 500 (mean age 16.25 ± 1.09) adolescents randomly selected from the northern border region of Saudi Arabia (KSA). The northern border region is sub-divided into three governorates: Ar'ar (186), Rafha (142) and Turayf (172)...

BACKGROUND: A Class II division 2 malocclusion is characterised by upper front teeth that are retroclined (tilted toward the roof of the mouth) and an increased overbite (deep overbite), which can cause oral problems and may affect appearance.This problem can be corrected by the use of special dental braces (functional appliances) that move the upper front teeth forward and change the growth of the upper or lower jaws, or both. Most types of functional appliances are removable and this treatment approach does not usually require extraction of any permanent teeth...

Fibrous dysplasia (FD) is a disturbance of the mesenchymal tissue that accounts for 2.5% of all bone tumors and more than 7% of nonmalignant bone tumors. In the craniomaxillofacial region, FD affects the calvaria, skull base, zygoma, and jaws, the prevalent site being the maxilla (50% of cases). Therapy for craniomaxillofacial FD is surgical. The goals of surgery are to prevent functional disorders and restore facial symmetry, volume, and contour. In this article, we present a case of a young female patient affected by right orbital-zygomatic-maxillary FD...
