Objective: The aim of this review is to summarize the effects of local and systemic PTH administration on periodontal tissues during orthodontic tooth movement. Materials and methods: An electronic search was conducted on the following databases: PubMed/MEDLINE, Google Scholar, SCOPUS and Embase. On PubMed/MEDLINE, the Medical Subject Headings (MeSH) keywords used were: “orthodontic tooth movement” OR (“tooth” (All Fields) AND “tooth movement” (All Fields)) OR “tooth movement” (All Fields)) AND (“parathyroid hormone”); all studies included using CONSORT. Results: After elimination of duplicates and articles not meeting our inclusion criteria, seven animal studies were included in this review. Although the majority of the studies suggest that PTH may a have a favorable outcome on OTM, most studies were found to have several sources of bias. Conclusion: Animal studies with minimal bias and long-term clinical studies are needed to ascertain the efficacy of intermittent PTH administration in improving the rate and retention of OTM.

Corticotomy-facilitated orthodontics is a clinical treatment modality comprising the application of conventional orthodontic forces combined with selective decortication of the alveolar process of the bone, which generates a localized process of bone remodeling (turnover) that enables accelerated orthodontic tooth movement. Compared with conventional orthodontic treatment, corticotomy-facilitated orthodontics is associated with reduced treatment time and reduces the frequency of apical external root resorption; however, this modality increases morbidity and financial costs. Although the clinical outcomes of corticotomy-facilitated orthodontics appear favorable, no results of evidence-based investigations of long-term outcomes are available in the literature, and the long-term effects of corticotomy-facilitated orthodontics on the teeth and periodontium are unclear. This narrative review discusses the biological events associated with corticotomy-facilitated orthodontics. Authoritative articles found in relevant databases were critically analyzed and the findings were integrated and incorporated in the text.

ABSTRACTRetention is the phase of orthodontic treatment which maintains teeth in their orthodontically corrected positions, following the cessation of active orthodontic tooth movement. Development of resin-impregnated, fiber-reinforced composite materials has provided the potential to develop new approaches for stabilizing teeth and replacing teeth conservatively. This case report describes the rehabilitation of a patient with orthodontic and prosthetic problems. The long-term behavior of glass fibers splint must be evaluated in clinical studies.

Retention is normally required after active orthodontic tooth movement in order to maintain tooth position and minimize the effects of age-related changes to the dentition. The aim of this article is to define stability, retention and relapse with reference to the literature and to review the evidence with regards to clinical effectiveness of different types of fixed and removable retainers and wear regimens, with emphasis on systematic reviews and Randomized Controlled Trials (RCTs). Furthermore, to discuss the general dental practitioner's role and responsibility in managing patients after active orthodontic treatment. CPD/Clinical Relevance: It is common practice for orthodontists to review patients for one year after active orthodontic treatment. Beyond this period, monitoring of the patient's long-term retention is often carried out in general dental practice. This paper provides an overview of orthodontic retention, including retainer types, wear regimens and a discussion of the common problems associated with retainers and advice on management.
