“…It is a reliable, noninvasive, reproducible method for assessing implant stability [14]. For this reason, RFA was used in this study to monitor stability changes during the osseous healing period to determine if the OD drilling technique can allow for maintaining high stability levels in the early weeks after implant insertion, which may thereby facilitate early loading, which is de ned as implant loading at least 48 hours but no later than 3 months after implant surgery [15].…”

Purpose In this study, the osseodensification (OD) drilling technique was used to assess the impact of implant site preparation on implant stability changes during the osseous healing period, insertion torque (IT), and preparation time.Methods In this randomized controlled clinical study, a total of 20 patients received 40 dental implants (DI), which were divided into two groups at random: the first group (the study group), which received the implants using the OD drilling technique, and the second group (the control group), which received the implants using the conventional drilling technique. Prior to surgery, bone density was assessed by CBCT. The Osstell implant stability quotient (ISQ) was used to measure implant stability immediately following implant insertion as well as 6 and 12 weeks later.Results There was no statistically significant difference in primary stability between the groups (P-value 0.216). In contrast, at 6 weeks and 12 weeks postoperatively, the control group showed higher ISQ values (P-values 0.002 and 0.005, respectively). There was no significant difference in the (IT) between the groups (P-value 0.627). The preparation time was significantly longer in the study group compared to the control group (P-value 0.0001).Conclusion The OD drilling technique did not show a more favorable outcome regarding the implant stability changes, IT, and preparation time over that of the conventional approach and resulted in a significant drop in stability after 6 weeks postoperatively, making OD use for early loading questionable.

“…From the statistical analysis performed, it appears that, for the analyzed cases, the degree of ossification (Ca/P ratio) was better represented for the immediate loading, compared to the late loading. Currently, immediate loading [14][15][16][17] is increasingly used with good long-term results, but also for the fastest possible reintegration of patients into society.…”

Objectives. The purpose of the present study was to evaluate by scanning electron microscope (SEM) and energy dispersive spectrophotometry (EDS), the degree of bone mineralization of the tissues on the surface of failure dental implants with immediate or late loading. Materials and method. In the study, 8 dental explants from 8 clinically healthy, non-smoking patients were taken. All implants were inserted by the same dental surgeon, 4 of them were immediate loaded and 4 were late prosthetically loaded by the same dentist. The ablation of the implants was performed as atraumatically as possible and they were collected in sterile containers and sent to the BIOMAT Research Center, where they were subjected to SEM and EDS analyses. The ratios between the chemical elements calcium and nitrogen (Ca/N), phosphorus and nitrogen (P/N), respectively calcium and phosphorus (Ca/P) were calculated for each of the 8 samples and were statistically analyzed. Results. If we compare the degree of coverage of the implants with bone tissue in different phases of mineralization, we find that the bone structures occupy a larger surface area of the implants in the cases with immediate loading compared to the cases with late loading. Thus, out of 4 immediately loaded implants, 2 were completely covered, one showed very little exposed areas, and the fourth showed alternating covered and uncovered areas. Regarding the late loaded implants, three showed alternation between covered and uncovered areas and only one was completely covered with bone. Conclusions. The degree of coverage of the explants with bone tissue was better represented for the immediate loading cases. The degree of mineralization of the bone tissue covering the explants was higher for cases with immediate loading. To confirm the obtained results, it is necessary to expand the study on larger batches of samples.

“…Since their discovery, titanium dental implants have completely changed therapeutic methods, created new opportunities for research, improved patients' quality of life, and increased the expectations of patients and dentists. Research in implantology soon specialized in various elds such as, for example, the in uence of implant surfaces on osteointegration [1][2][3][4][5][6][7][8], preparation of the implant sites [9][10][11][12][13][14], immediate implant into the extraction sockets [15][16][17][18][19], and early or immediate loading [20][21][22][23][24][25][26].…”

BackgroundTo avoid cortical compression, several implant systems have included dedicated drills aimed at widening the cortical region of osteotomy. However, the manual execution of this operation does not guarantee the necessary precision. Hence, the present study aimed to determine the optimal size of the recipient site at the level of the alveolar crest in relation to the size of the coronal region of the implant to achieve the best healing result. Materials and methods: Blades of different diameters were incorporated into the coronal part of the implant to prepare the cortical region of the bone crest in different dimensions in relation to the collar of the implant. The differences in diameter of the blades in relation to the collar of the implant were as follows: one control group, -175 µm, and three test groups, 0 µm, + 50 µm, or + 200 µm. Results: The marginal bone loss (MBL) at the buccal aspect was 0.7 mm, 0.5 mm, 0.2 mm, and 0.7 mm in the − 175 µm, 0.0 µm, + 50 µm, + 200 µm groups, respectively. The differences were statistically signi cant between group + 50 µm and control group − 175 µm (p = 0.019), and between + 50 µm and + 200 µm (p < 0.01) groups. The level of osseointegration at the buccal aspect was more coronally located in the test groups than in the control group, whereas the bone-to-implant contact percentage was higher in the + 50 µm and + 200 µm groups. However, these differences were not statistically signi cant. Conclusions: The lowest bone crest resorption and highest levels of osseointegration were observed in the 0.0 µm and + 50 µm groups. Only the difference between the + 50 µm and control + 200 µm groups was signi cant. The cortical region where the blades had performed their cutting action showed regular healing with perfect sealing in all the groups. Cortical blades gathered bone particles, particularly in the + 200 µm group, which were incorporated into the newly formed bone. The results from the present experiment provide support to the use of blades that produce a marginal gap of 50 µm after implant insertion.
