“…The cutting efficiency of a rotatory implant drill is clinically relevant, and the surface roughness and loss of sharpness at the cutting edge and corner of the drill can predict the cutting efficiency and durability. [15,32,[40][41][42] RMS deviation of the drill profile is an accurate way to evaluate the surface roughness, which depends on the average of a set of individual measurements of the peaks and valleys of a surface. [14,[43][44][45] In the present study, the RMS surface roughness, loss of sharpness, and abrasion of the pilot drills were evaluated using SEM and AFM.…”

The aim of the present study was to observe the abrasion of implant drills and postoperative reactions for the preparation of the interradicular immediate implant bed during the COVID-19 pandemic and beyond. Thirty-two implant drills were included in four groups: blank, improved surgery, traditional surgery, and control. In the improved surgery group, a dental handpiece with a surgical bur was used to decoronate the first molar and create a hole in the middle of the retained root complex, followed by the pilot drilling protocol through the hole. The remaining root complex was separated using a surgical bur and then extracted. Subsequently, the implant bed was prepared. Implant drills were used in the traditional surgery group to complete the decoronation, hole creation, and implant-drilling processes. The tooth remained intact until the implant bed was prepared. The surface roughness of the pilot drill was observed and measured. Surgery time, postoperative reactions (swelling, pain, and trismus), and fear of coronavirus disease 2019 scale (FCV-19S) were measured and recorded, respectively. Statistical analysis revealed significant difference with surface roughness among blank group (0.41 ± 0.05 μm), improved surgery group (0.37 ± 0.06 μm), traditional surgery group (0.16 ± 0.06 μm), and control group (0.26 ± 0.04 μm) ( P < .001). Significant differences were revealed with surgery time between improved surgery group (5.63 ± 1.77 min) and traditional surgery group (33.63 ± 2.13 min) ( P < .001). Swelling, pain, and trismus (improved group: r ≥ 0.864, P ≤ .006; traditional group: r ≥ 0.741, P ≤ .035) were positively correlated with the FCV-19S. This study proved that a new pilot drill could only be used once in traditional surgery but could be used regularly in improved surgery. Improved surgery was more effective, efficient, and economical than the traditional surgery. The higher FCV-19S, the more severe swelling, pain, and trismus.

“…Heat generation during osteotomy preparation may result in a zone of devitalized bone around the osteotomy; a condition that may affect implant osseointegration. (30,31) This can be explained due to the fact that survival of the bone cells is highly influenced by the amount of heat generated during drilling. (32) Drilling was also carried out in an up and down motion to allow irrigation to pass through the metallic sleeves and soft tissue to reach the osteotomy site and provide sufficient cooling.…”

Purpose: The purpose of this study was to evaluate the effect of Desktop scanning protocol on accuracy of guided implant placement in completely edentulous patients.Methodology: Twenty four completely edentulous patients were selected for implant placement. Complete dentures were made for all the patients. Radioopaque markers were added to the dentures to be used as a radiographic stent. A Cone beam CT scan was then made for each patient while wearing the radiographic stent. The patients were then randomly divided into 2 equal groups. In the first group, a CBCT scan was made for the radiographic stent. In the second group, desktop scanning was made for the radiographic stent while being seated on the patient's cast and another scan for the patient's cast. After implant insertion, CBCT scan was made for each patient while wearing the radiographic stent. Superimposition of CBCT scans pre and post implant insertion was made. Deviations between planned and placed implant were measured in the lateral apical, lateral coronal and angular aspects.Results: Non statistically significant difference between radiographic and desktop scanning on implant deviation was observed. Conclusion:within limitation of this study, effect of both scanning protocols on the lateral apical, lateral coronal and angular deviations of placed implants is comparable.

“…High temperature during osteotomy site preparation causes bone necrosis and affects implant osseointegration. (10,11) Based on theoretical analysis and Finite Element Analysis simulation, the temperature distribution of the drilling area in the placement of dental implants under surgical guide was determined at average depth of 8mm. (12) The mean maximum temperatures were the highest (about 39.8 •C) was found at a depth of 9 mm in another study (13) .On the other hand, a study did not find a significant difference in the mean maximum temperature generated in the osteotomy sites prepared by surgical guides or free hand.…”

Aim of the study: This study was conducted to assess the efficacy of different guided surgery protocols on mean marginal bone loss around implants in implant assisted mandibular over denture.Materials and methods: Twenty-one edentulous patients were selected for this study. They were randomly divided into three different groups. In the first group implants were placed by free hand technique. In the second group partial limiting surgical guide was used; the surgical guide was used for pilot drilling. In the third group completely limiting surgical guide was used; the surgical guide was used for the whole drilling sequence. Mean marginal bone loss was measured using CBCT at 6 months, 12month and 18 months interval. Results were collected and tabulated for statistical analysis.Results: One-way ANOVA test showed no statistical significance between the three groups in all time intervals. Conclusion:Within the limitation of this study, no statistically significant differences could be found between the guided groups and the free hand group at the 18 months follow-up period.
