“…Before retention evaluation, artificial saliva (Saliveze TM -Wyvern Medical LTD-UK) was applied to the models and the inner side of the overdentures framework to mimic the oral environment [26]. Retention was estimated by a digital force gauge (Nextech DFS500-Nextech Global-Thailand) used to record maximum dislodging forces [27], [28] (Fig. 8).…”

Background: Retention and stabilization of implant-supported overdenture is associated with more patient satisfaction, chewing capability, and oral health-related quality of life. There are a variety of implant retention systems which can be utilized to retain an implant overdenture. Telescopic attachments provide excellent retention resulting from friction. Objective: This study evaluates the retention force and fatigue resistance of ready-made polyether ether ketone (PEEK) telescopic attachment in different numbers and positions of dental implants in palateless maxillary overdenture. Method: Five edentulous maxillary models were fabricated from cold-cure poly methyl methacrylate resin. The study models were divided into two groups; the first group (3-implant supported overdenture) and the second group (4-implant supported overdenture). Each group is subdivided into subgroups according to the different implant positions. One palateless maxillary denture was constructed over each model. Ready-made PEEK telescope attachments correspond to implant abutments embedded in the inner surface of these overdentures. Initial anterior, posterior, and central retention values of overdentures were estimated and compared with the retention after 540 cycles of insertion and removal using a digital force gauge. One-way ANOVA testing was used to compare the means of the models of group one, an Independent sample t-test was used to compare the means of the models of group two, and a comparison of retention value between the groups and Paired sample t-test was applied for determining the difference between initial and secondary retention value (p<0.05). Results: The anterior retention value was significantly decreased when the dental implants were placed distally while the posterior and central retention values were significantly increased. Also, retention value increased as implant number increased; the lowest mean retention values were recorded with Group one and the highest values were with Group two. The final retention value was significantly decreased after 540 times insertion and removal. However, the values of secondary retention are still larger than the minimum retention value that was reported (5–7 N) to achieve sufficient patient satisfaction. Conclusion: The implant location and number affect the retention value of palateless maxillary overdenture. Continuous insertion and removal of the prosthesis for daily hygiene practice lead to decreases in retention values.

“…Hal ini terjadi karena hilangnya kontak antara tepi GTP rahang bawah dengan jaringan dasar mulut dan pergerakan lidah yang mengakibatkan kehilangan fungsi lingual border seal, sehingga mengakibatkan GTP rahang bawah kurang retentive. 16 Hal ini juga dapat dikaitkan dengan atropi pada mandibula yang terjadi lebih cepat dibandingkan rahang atas sehingga memberikan dampak berkurangnya retensi GTP. Teknik penyusunan gigi geligi serta memposisikan basis GTP pada posisi neutral zone adalah teknik paling efektif untuk menghindari GTP rahang bawah menjadi tidak retentif.…”

The most common complaint reported by patients in denture wearing is loose denture, caused by lack of retention. In the complete denture wearing, saliva plays an important role in retention. A well-fitting denture base to supporting tissues and the presence of adequate border seals will provide optimal denture retention. This condition can be achieved if it is supported by adequate volume, flow, and consistency of saliva. The purpose of this study is to determine the relationship between flow rate and viscosity of saliva with complete denture retention in Andalas Dental Collage and Hospital. This study used a cross sectional design. Thirty patients of complete denture wearers at the Andalas Dental Collage and Hospital were included in this study. Samples were selected through consecutive sampling method. Data were collected by using medical records, saliva viscosity assesstment, salivary flow rate measurement, and complete denture retention examination. Data were analyzed by Mann Whitney tes with p< 0,05. There was a significant relationship between salivary flow rate and maxillary complete denture retention (p= 0,002) and there was a significant relationship between saliva viscosity and maxillary complete denture retention (p= 0,002). However there was no relationship between salivary flow rate and mandibular complete denture retention (p= 0.101) and there was no relationship between saliva viscosity and mandibular complete denture retention (p= 0,223). The conclusion of this study was that the flow rate and viscosity of saliva was associated with maxillary complete denture retention yet was not associated with mandibular denture retention.

Brief Background The purpose was to compare and evaluate border moulding using two different materials on mandibular edentulous arches. Materials and Methods This clinical study was performed on 15 healthy edentulous subjects who reported to the department of Prosthodontics. All the subjects were first given complete dentures, fabricated with low fusing compound as the border moulding material, followed by complete dentures with putty as the border moulding material. Retention was measured at 3 stages: Border moulding; Complete denture insertion; 6 weeks follow up. Patient’s satisfaction was measured with a 10 point visual analogue scale for both the dentures pre treatment and at the follow up visit. Results Putty border moulding showed higher retention as compared to low fusing compound border moulding with significant difference at all stages- stage 1 (p=0.011), stage 2 (p=0.009) and stage 3 (p=0.0054). The time taken for border moulding was significantly lower in Group 2 than Group 1(P=1.6E-48). According to VAS scores, in terms of aesthetic and comfort parameters, patients were satisfied in both groups without any significant difference, however, retention in Group 2 was higher as compared to group 1(P=0.05) Summary and Conclusions There was a statistically significant difference in the retention, between the groups. Group 2( Putty) had higher retention compared to Group 1(low fusing compound).Time taken for border moulding was significantly lower for Group 2( putty). No significant difference in patient’s satisfaction was observed for aesthetic and comfort parameters. In functional parameter, retention was better in Group 2(putty) subjects. Key Words: Low fusing compound, PVS (putty), border molding, mandibular edentulous arch.
