“…The insertion torque value in this study showed broader (10 to 50 N cm) than the previous publication (Table 2 ) [ 22 , 32 ], and the cause of reasons for the difference are as follows: Primary stability may be affected by the bone quantity and bone quality in the treatment area, the micro- and macro-level design of the implant body, and the accuracy of the surgical technique [ 18 , 25 ]. In this study, the 17 dentists performed implant treatment.…”

“…All numerical data obtained in this research were statistically analyzed with one-way analysis of variance and multiple comparison tests by Bonferroni et al [ 22 ]. Fisher’s exact test and the corresponding t test were used for statistical analysis of insertion torque values and the relationship between ISQ and insertion torque, respectively [ 23 ].…”

BackgroundA current implant body surface was treated with “rough processing” by sandblasting and acid etching for the purposes of obtaining more reliable osseointegration and shortening the treatment period. Various reports have examined the healing period with the use of these implant bodies, but a consensus opinion has not yet been obtained. The purpose of this study is to evaluate the relationship between insertion torque (IT) and implant stability quotient (ISQ) at implant treatment using the current rough-surfaced implant. We evaluated the implant treatment sites with ISQ values, IT values, and voxel values.MethodsParticipants in this study comprised 26 patients (10 males, 16 females; mean age, 55.5 years) who received posterior region dental implants at Tokyo Dental College Hospital or Fukuoka Dental College Hospital. For all participants, pretreatment computed tomography and determination of bone quality from voxel values were performed. Thirty-two implant bodies were inserted into the posterior region, and insertion torque was measured. ISQ was also measured at 0, 2, 4, 6, 8, and 12 weeks postoperatively.ResultsEight implant bodies in the maxilla and 24 in the mandible were inserted. All ISQ values increased, exceeding 60 by 6 weeks postoperatively. For insertion torque < 30 N cm, ISQ increased significantly after 8 weeks. For ≥ 30 N cm, the ratio at which high ISQ values appeared increased significantly after 6 weeks. Compared with the treatment area with insertion torque < 40 N cm, the treatment area ≥ 40 N cm showed a significantly higher voxel value.ConclusionsNo significant relationship was found between the insertion torque value and the ISQ value. Also, it was suggested that the ISQ value was considered to be an important indicator for observing the treatment state of the implant.

“…Various factors that influence the success and failure of any implant rehabilitation are the type of surgical technique, primary implant stability, and volume and quality of bone around the implant. [ 23 ] One hundred percent survival rate of solitary implants after 1 year was depicted in the results of this study regardless of the surgical technique. This is comparable with other clinical trials which depicted equal survival rates of both flapless and flap surgery groups.…”

“…Few authors have advocated that placing implants with a minimally invasive technique not only reduced the trauma but also maintains the tissue volume. [ 21 - 23 ] Cannizzaro et al . [ 14 ] have greatly emphasized the benefits of the flapless technique in terms of minimal trauma and better acceptability.…”

Aim: The study was aimed to evaluate circumferential crestal bone level after one year of implant placement with flapless versus flap surgery using surgical template after immediate loading in the posterior mandibular region using CBCT. Setting and Design: The study was designed as a Randomized controlled trial. Material and Methods: 32 implants were placed in single edentulous spaces in the mandibular posterior region after random allocation into two groups: Flap surgery (Group A) and Flapless surgery (Group B). Virtual implant planning was performed using Blue Sky Bio software, and static CBCT guided 3D printed surgical templates were fabricated for all participants of both the groups. Immediate non-functional temporization was performed. Circumferential crestal bone levels were assessed after surgery and one-year follow-up using CBCT and XELIS software. Vertical bone loss (VBL) and horizontal bone loss (HBL) was assessed on four sides: buccal, lingual, mesial and distal. Statistical Analysis Used: Data was analyzed using Statistical Package for Social Sciences IBM Corp. Released 2017, IBM SPSS Statistics for Windows, Version 25.0. (Armonk, NY: IBM Corp.) and Graph Pad Prism 7.0 version. The level of significance was chosen <0.05. Chi square test was performed to assess the difference in the age in the two groups. Mann-Whitney U test was performed to compare the two groups for outcome measure. Graphically, quantile-quantile (Q-Q) plot was made using mean and standard deviation for normality verification of data. Results: 100% survival rate and patient compliance was observed along the one-year follow-up duration. By using Mann-Whitney U test, statistically significant difference was found in the vertical bone loss among participants of Flap surgery (Group A) and Flapless surgery (Group B) on all the four sides after one year of implant placement. However, significant results were not obtained for the difference in the horizontal bone level. Conclusion: Within the limitations of this study, vertical bone loss measured circumferentially was more positively correlated with the implants placed with flap surgery compared to flapless surgery after immediate loading in the posterior mandibular region after one year.

“…And in the flapless technique, bone vascularization is preserved. Once the periosteum is stripped, there is a definite loss of blood supply to the crestal bone leading to increased bone loss which is found in the flap technique [ 9 , 10 ].…”

Background: The use of flapless surgery for placing dental implants is extremely popular due to better radiological tools and the availability of software that help in the planning of dental implants. Objective: The present study was done to assess crestal bone loss by using flapless and flap techniques for placing implants. Methods: A total of 50 subjects who satisfied the inclusion criteria were selected for this study. Selected patients were then divided equally into two study groups i.e., those who are and those who are not undergoing flap surgery. Statistical analysis was done using the Mann-Whitney U test. Results: Statistically considerable P values were obtained. Bone loss was lesser with the flapless technique. Conclusion: Flapless implant placement demonstrated less crestal bone loss compared to flap surgery.

Flapless versus open flap techniques of implant placement: A 15-month follow-up study

Abstract: Both techniques showed a reduction in CBH with time but the flapless technique showed a lesser reduction. Therefore, the flapless technique can be considered as a better treatment approach for placement of implants, especially where adequate width and height of available bone are present.
