Aim:
The purpose of the study is to evaluate and compare the horizontal mandibular positions recorded between intraoral conventional tracer and intraoral digital tracer in upright and supine position.
Materials and Methods:
Twenty-four edentulous patients with well-formed ridge and adequate interarch distance space were selected. MATLAB software was assimilated with intraoral digital tracer and was utilized in the study for recording the horizontal movements of the mandible, i.e., gothic arch tracing by intraoral digital tracer and was observed on a laptop with the help of MATLAB Software. For each subject, multiple mandibular readings were recorded and analyzed through software, and similar readings were recorded with conventional intraoral tracers. The comparison between intraoral conventional tracer and intraoral digital tracer was done to assess the reliability. Moreover, the consistency of recording horizontal mandibular position was also compared between upright and supine position.
Results:
The data were procured and utilized in comparison for different positions revealed statistically significant difference by using Student's Paired
t
-test. The test resulted in supine position better compared to upright position (
P
= 0.0001). The association between supine position with upright position was calculated using Fischer's exact test, and it was also found to be statistically significant (
P
= 0.002). The Pearson's Correlation analysis was performed to check the agreement between upright and supine position and very weak downhill correlation (
r
2
= −0.130) was observed between the two variables.
Conclusion:
On evaluation and comparison of horizontal mandibular position, it was found that the intraoral digital tracing technique is more valid compared to conventional intraoral tracer technique. It was also observed that the consistency of reproducibility in recording horizontal mandibular position in supine position is significantly higher than upright position.
Magnets have been used widely in the field of dentistry for many years with some success, as they can be manufactured in small dimensions as a retentive devices in overdenture technique, maxillofacial prosthesis and obturators. These magnet attachment attached to osseointegrated implants which transfer the occlusal load to the bone, thereby prevent resorption of remaining alveolar bone and improves the retention and stability of the denture. Magnetic assembly consist of magnet and ferromagnetic metal keeper. More recently, magnets have been made from alloys of the rare earth elements samarium and neodymium, which provides stronger magnetic force per unit size. Magnets are sealed by means of the latest laser lasing techniques thus protect magnet from corrosion in oral cavity. The present article demonstrates the rehabilitation of completely edentulous patient with the help of implant supported mandibular overdenture with magnet attachment and conventional maxillary denture.
Burns of head and neck region causes skin contracture which will result in microstomia and loss of skin flaccidity. The prevention and management of microstomia contracture is an important aspect of facial burn. The goal of microstomia repair include the reconstruction of orbicularis sphincter for adequate lip functioning, obtaining lip symmetry and well positioned scar and adequate mouth opening. The standard treatment for the prevention and management of contracture includes compression therapy, grafting, mouth splinting, scar massage, excercise, patient education. These types of maxillofacial prosthetic appliances may be indicated, in conjunction with or without surgery these appliances can be use to improve the reduced mouth opening caused by burns or other traumatic injuries With proper education and motivation of operator and the patient use of these appliances will not only improve the reduced mouth opening but also improve form, function, esthetics, and also enhance the patient’s quality of life.
