Aim: Closed hollow obturators are often fabricated to provide adequate retention, stability and comfort for the patient.Background: Rehabilitation of patient with maxillary obturator is the most common treatment option after maxillectomy. However, the heavy weight of obturator often leads to discomfort and problem in its retention.Case report: This article presents rehabilitation of a patient after the surgical removal of desmoplastic ameloblastoma. It employs a simple procedure to create a closed hollow obturator with uniform and adequate thickness of prosthesis wall. Conclusion:The technique offers advantage since it is easily fabricated with routinely used materials in a short time.

We present the management of a case of Type II dens invaginatus in a mandibular premolar with a large invagination in the coronal third of the root on mesial aspect of the crown in proximity of cementoenamel junction significantly compromising the strength of the crown structure. We describe in detail the various measures taken to assess the internal tooth structure destruction and enhance the fracture resistance of the involved premolar. The case has a long-term follow-up of 36 months showing clinical and radiographic signs of healing. We highlight use of a simple “foil coated fiber postblocker technique” for root reinforcement in the first premolar. Successful management of teeth with dens invaginatus can be effectively done using with careful treatment planning and selection of reinforcing adhesive restorative materials.

Statement of Problem: Medium body polyether impression material has been recently used as neutral zone recording material. However, there is a lack of studies comparing it with routinely used material. Purpose: The purpose of the study is to compare neutral zone width of phonetic (PNZ) and swallowing (SNZ) neutral zone impression techniques with a tissue conditioner and a polyether impression material within the same subjects. Materials and Methods: Assessments of neutral zone width were carried out in ten completely edentulous patients with advanced mandibular resorption. On each patient, four neutral zone impressions were recorded as follows: SNZ with tissue conditioner material, PNZ with tissue conditioner material, SNZ with polyether impression material, PNZ with polyether impression material. Putty indices were made of each neutral zone and traced on graph paper. The buccolingual measurements were made at five different locations, midline, right first premolar, left first premolar, right first molar, and left first molar. Statistical analysis was done using Mann–Whitney U test. Results: There was no significant difference observed when comparison was done either between materials or techniques. Conclusion: Medium body polyether can be a viable alternative to conventional tissue conditioner material and can be used with both swallowing and phonetic techniques with equal efficacy.
