Alternative Method for Full Oral Rehabilitation in Patients with Pycnodysostosis Syndrome: A Case Report

Clinical and radiographic characteristics of pycnodysostosis: A systematic review

Purpose

Pycnodysostosis (PYCD), an autosomal recessive syndrome, is characterized by an imbalance in bone remodeling that produces various clinical and radiographic craniofacial manifestations. This review represents a systematic examination of these manifestations, as well as oral features associated with PYCD.

Materials and Methods

A systematic review was conducted across 8 databases from February to March 2023. The search strategy focused on studies reporting cases of PYCD that examined the clinical and radiographic craniofacial and oral characteristics associated with this syndrome.

Results

The review included 84 studies, encompassing a total of 179 cases of PYCD. More than half of the patients were female (55.3%), and the mean age was 14.7 years. Parental consanguinity was reported in 51.4% of the cases. The most common craniofacial clinical manifestation was a prominent nose, observed in 57.5% of cases. Radiographically, the most frequently reported craniofacial characteristics included the presence of an obtuse mandibular angle (84.3%) and frontal cranial bosses (82.1%). Clinical and radiographic examinations revealed oral alterations, with micrognathia present in 62.6% of patients and malocclusion in 59.2%. Among dental anomalies, tooth agenesis was the most commonly reported, affecting 15.6% of patients.

Conclusion

Understanding the clinical and radiographic craniofacial features of PYCD is crucial for dental professionals. This knowledge enables these clinicians to devise effective treatment plans and improve patient quality of life.

Advanced method of rehabilitating edentulous Jaws: A review of telescopic denture

BACKGROUND

Edentulism conducts to a recognized impairment of oral function with both aesthetic and psychological changes. These patients suffer from a multiplicity of problems with their dentures, such as insufficient stability, retention and pain during mastication. The rehabilitation of a part edentulous patient can be established using a wide range of prosthetic treatment options. The overdenture treatment uses a removable total denture that overlies retained teeth, tooth roots, or dental implants. In the literature it was shown that patients with removable overdentures supported and retained either by tooth roots or implants have more predictable prosthodontic outcomes.

OBJECTIVE

The aim of this review is to provide an overview on the overdenture with a focus on the tooth-supported telescopic overdenture.

METHODS

The literature research was performed in the Scopus, Web of Science, and Pubmed electronic databases. Document type was limited to papers written in English, without time restrictions. The Review was recorded in the international PROSPERO (International Prospective Register of Systematic Reviews) database with the following number CRD42022326415.

RESULTS

A total of 256 articles published were found from electronic searches, Two independent reviewers carried out the screening and the selection process for the studies. First, duplicate citations were eliminated. Then, the two Authors independently screened the retrieved articles by title and abstract of each citation to determine its suitability for inclusion. Finally, 13 full-text articles satisfied the inclusion criteria.

CONCLUSION

Prostheses supported by Frictional telescopic crowns offer an effective treatment alternative for patients with Severely reduced dentitions who do not want implant treatment or complete dentures.

Pycnodysostosis- a rare disorder with distinctive craniofacial dysmorphia. A case report

Pycnodysostosis is a rare autosomal recessive condition caused by the mutation of CTSK gene. CTSK regulates the activity of Cathepsin K which is responsible for osteoclast-mediated bone resorption. This mutation causes the bones to become dense, sclerotic, brittle, and thus, prone to fracture. Affected individuals have normal cognitive development and life expectancy, however, the quality of life depends on the early diagnosis of the condition. The patient presents with striking clinical (short stature, brachydactyly) and radiological (frontal and parieto-occipital bossing, open sutures, and fontanelles, acro-osteolysis of terminal phalanges) features making the diagnosis clinico-radiographic. In atypical or mild cases with overlapping features, gene mapping is advocated. A plethora of dental anomalies and characteristic craniofacial dysmorphia puts the dentist in a position to diagnose such a case.
