Autotransplantation of a surgically removed canine using a customised 3D-printed surgical template.

Autotransplantation is a treatment option with high reported survival rates to replace failing teeth in the anterior maxilla. This treatment requires a multidisciplinary approach from orthodontists, paediatric dentists, restorative dentists, and oral and maxillofacial surgeons to achieve successful outcomes. Success is dependent on many factors including stage of root development, handling of the periodontal ligament, extra-alveolar time and splinting.

Potential reformatting errors in cone-beam computed tomography for dentoalveolar surgery: a cautionary tale.

We describe the removal of a lower second molar tooth in which preoperative cone-beam computed tomography (CBCT) showed that the inferior alveolar nerve (IAN) was encased in the distal apex of the root of the tooth. During operation the nerve was found to be entirely separate from the apex of the root and not involved. With the wider use of CBCT in the treatment planning of dentoalveolar surgery, this case represents a cautionary tale to the clinician on reliance on clinical imaging and software in guiding the decision making process.

Facial shape and asymmetry in 5-year-old children with repaired unilateral cleft lip and/or palate: an exploratory study using laser scanning.

To investigate the feasibility of facial laser scanning in pre-school children and to demonstrate landmark-independent three-dimensional (3D) analyses for assessment of facial deformity in 5-year-old children with repaired non-syndromic unilateral cleft lip and/or cleft palate (UCL/P). Faces of twelve 5-year-old children with UCL/P (recruited from university hospitals in Cardiff and Swansea, UK) and 35 age-matched healthy children (recruited from a primary school in Cardiff) were laser scanned. Cleft deformity was assessed by comparing individual faces against the age and gender-matched average face of healthy children.

Removable rapid maxillary expansion.

A novel removable rapid maxillary expansion appliance is described for use in routine clinical practice. The laboratory construction and clinical technique is described, and the advantages of the appliance over conventional rapid expansion devices are highlighted.

The use of implants for anchorage in the correction of unilateral crossbites.

The provision of orthodontic anchorage in the adult patient can be compromised due to reduced periodontal support, insufficient number of teeth and limited supra-gingival tooth tissue. Where tooth borne anchorage is unavailable for significant orthodontic movement implants represent a viable alternative. This paper describes the use of dental implants for orthodontic anchorage in a partially dentate patient with a severe unilateral cross-bite where orthognathic surgery was the only other realistic option.

A comparison of plaster, digital and reconstructed study model accuracy.

Objectives: To evaluate the accuracy and reproducibility of a three-dimensional (3D) optical laser-scanning device to record the surface detail of plaster study models. To determine the accuracy of physical model replicas constructed from the 3D digital files.

Design And Setting: A method comparison study using 30 dental study models held in the Orthodontic Department, School of Dentistry, Cardiff University.

Modern restorative management of patients with congenitally missing teeth: 4. The role of implants.

Unlabelled: In this fourth and final paper on the management of patients with congenitally missing teeth, the use of dental implants is considered. This group of patients often provides unique challenges when implant reconstruction is considered. Often a multidisciplinary approach is required involving orthodontists, oral surgeons and restorative dentists.

Modern restorative management of patients with congenitally missing teeth: 3. Conventional restorative options and considerations.

Restoration of spaces in hypodontia patients needs to take into account many factors including, the number of missing teeth, the distribution of space, the size of the teeth, and the age of the patient. This paper considers adhesive and conventional bridgework, as well as removal alternatives for the restoration of spaces. The various merits of each are discussed, together with treatment planning considerations for such cases.

Modern restorative management of patients with congenitally missing teeth: 2. Orthodontic and restorative considerations.

Managing edentulous spaces in patients with congenitally missing teeth demands careful planning and, often, a multidisciplinary approach. Orthodontic tooth movement can be considered to close spaces as well as improve the distribution of available teeth. In this second paper, the advantages of a collaborative approach are discussed.

Is amelogenesis imperfecta an indication for renal examination?

Background: The term 'amelogenesis imperfecta' (AI) describes a diverse group of hereditary conditions primarily affecting the quality and/or quantity of dental enamel.

Case Report: This paper describes a case in which hypoplastic AI with delayed/failure of eruption of the permanent teeth was shown to be associated with renal calcification.

Conclusion: Given the importance of the renal involvement, the authors suggest that paediatric dentists consider referring all children with this dental phenotype for renal ultrasound examination.

Modern restorative management of patients with congenitally missing teeth: 1. Introduction, terminology and epidemiology.

The management of patients with congenitally missing teeth can be a challenge and, in many cases, requires multidisciplinary care. In this four-part series, a contemporary approach to managing this group of patients is discussed. This first paper examines the terminology, epidemiology and restorative challenges that such patients can exhibit.

The 3-dimensional construction of the average 11-year-old child face: a clinical evaluation and application.

Purpose: This article describes construction of the average face and its application in the clinical environment.

Subjects And Methods: A total of 72 children, mean age 11.8 years, were selected for the study.

The effect of topical fluorides on decalcification in patients with fixed orthodontic appliances: a systematic review.

Introduction: Decalcification is a significant problem during fixed orthodontic treatment. Topical Fluorides can reduce or eliminate the problem, but the relative effectiveness of different treatments or combinations of topical fluoride preparations is unknown. This systematic review was undertaken to determine the effectiveness of topical fluoride preparations in preventing decalcification during fixed orthodontic treatment.

Reliability of measuring facial morphology with a 3-dimensional laser scanning system.

Introduction: The purpose of this prospective clinical trial was to evaluate the reliability of a 3-dimensional facial scanning technique for the measurement of facial morphology.

Methods: A field study was conducted in 2 comprehensive schools in the South Wales region of the United Kingdom. Forty subjects, mean age 11 years 3 months, were analyzed for soft tissue changes at baseline (T1), within 3 minutes (T2), and 3 days later (T3) by using 2 commercially available Minolta Vivid 900 (Osaka, Japan) laser-scanning devices assembled as a stereo pair.

Management of obstructive sleep apnea in an edentulous patient with a mandibular advancement splint: a clinical report.

Literature on the treatment of obstructive sleep apnea in edentulous patients with a mandibular advancement splint is sparse. This clinical report describes a clinical and laboratory method of splint fabrication and discusses the rationale for its use.

The influence of cavity shape on the stresses in composite dental restorations: a finite element study.

Dental restoration adhering to the cavity exhibits fundamentally different load transfer mechanisms from non-adhering restorations. It is therefore questionable that traditional cavity designs are optimal from a purely mechanical point of view when working with composite materials. Drawing from general engineering experience, it can be hypothesised that smooth, well rounded designs with bevelled margins are superior.
