“…The factors affecting the insertion torque are -bone density, quality and quantity and hardness, using undersized drills and tapered designed implants. 19 Primary stability of implants is influenced by two main factors which include residual bone at implant interface and the function of compressive stresses at the interface of implant-tissue. These stresses may prove useful to enhance implant's primary stability, but they can attain a elevated level that may cause necrosis and localised ischemia of the bone at the surface of implanttissue.…”

“…9 Torque has a direct relationship with the density of the bone. 19 At the time of placement of an implant the insertion torque plays a prime role to determine the initial stability, which serves as an essential factor for osseointegration of implants and immediate loading. 20 The level of torque is generally expressed in Newton centimeters (Ncm).…”

“…11,30 Thus, several studies have been done to determine the association between insertion torque and bone related changes and have concluded a positive correlation between the two.

[31][32][33] Osseointegration is a structural and functional association between living bone and the loading implant interface, is crucial for implant stability, and is well thought-out a requirement for implant loading and clinical success of end osseous dental implants in long run.…”

Introduction: Insertion torque imposes a direct effect on the stability of implants. Some studies suggest that high torque has resulted in bone necrosis while some suggest no impact on bone with high torque, the literature regarding insertion torque relationship to changes in bone is sparse. Purpose: The rationale of this article is to critically evaluate the available scientific data on influence of insertion torque on implant success. Materials and Methods: A Medline and manual search was done to recognize studies that are concerned with insertion torque related implant success rates from 1970 to 2017. The articles taken in this study includes data on insertion torque such as primary stability, bone quality and quantity, implant design and changes in bone related to high or low torque. Results: The 28 included studies contains one randomized controlled trial, 12 prospective studies and 10 retrospective studies. Conclusion: Insertion torque leads to primary stability of implants which ultimately contributes to implant success.

“…Implant insertion success differs from site to site and patient to patient, but depends on the material, biocompatibility, implant design, patient factors, tissue health, bone quality and quantity, issues of the procedure such as insertion torque, load moment, duration of healing, biomechanical load and prosthetic design [1,2].…”

“…Factors that affect the insertion torque are bone density and hardness, the use of insufficiently sized drills, and the design of the conical implant. Torque is directly proportional to bone density (type D-1 bone is the highest and type D-4 is the lowest) [2]. Some authors point out that there is no established minimum torque to be used to achieve the primary stability of the implant.…”

Incomplete Implant Insertion Due to the Use of A Non-dynamometric Torque Wrench: A Case Report

A case is reported in which the use of a non- dynamometric torque wrench could be the cause of incomplete implant insertion. A woman, 73-year-old, visited the dentist in March 2021 for oral rehabilitation due to the absence of teeth in the left mandibular area. A Galimplant IPX 4.5 x 8 implant (internal hex connection) (Sarria, Spain) was placed in position 36. Bone drilling was performed correctly in width and depth, however, insertion of the implant was difficult due to the hardness of the cortical bone. New drillings were made in the bone with insertion and removal of the implant on three occasions. On the third occasion, the implant was threaded to a depth of 7 mm. At that time, the thread that the implant had carved in the bone had been lost and the implant did not advance until 8 mm in depth, nor could it go back to remove it and continue drilling the bone. We estimate that a dynamometric torque wrench should have been used during implant insertion, to provide adequate torque and not cause the loss of the thread that the implant had carved into the bone. The use of a non-dynamometric torque wrench does not allow a precise insertion torque. If excessive torque is applied, the thread carved by the implant in the bone can be lost and this finally causes an incomplete insertion of the same.

Objectives Assessment of the clinical performance of a porcine dentin-derived particulate bone graft material for bone regeneration after tooth extraction with implant placement at 4 months, in comparison to a commercially available porcine bone-derived graft. Material and methods This study was a randomized, parallel-group, semi-double-blinded clinical trial evaluating the clinical safety, tolerability, and performance of Ivory Dentin Graft™ in comparison with a commercial bone-derived material in alveolar ridge preservation following tooth extraction (registered at ClinicalTrials.gov, May 12th, 2017, Identifier NCT03150472). Extraction sites were grafted with test or comparator material and a titanium implant placed at 4 months after taking a graft site biopsy. Primary endpoints were the extent of new bone growth and bone-graft integration at 4 months. Results The dentin graft material had statistically significantly more new bone formation (60.75% vs 42.81%, p = 0.0084, N = 20 vs 16), better bone-graft integration scores (good integration in 85% vs 40%, p = 0.0066), and higher mean radiodensity of the bone (981.5HU vs 727.7HU, p = 0.0011) at the graft site compared to the bone-derived material. The mean implant insertion torque force was similar for the dentin and bone materials (34.75 Ncm vs 34.06 Ncm). Titanium implant placement was successful in 95% of patients with the dentin graft material compared to 81.25% for the bone graft. Both materials had similar clinical safety and tolerability as determined by adverse events and local site reactions. Physician-assessed ease of grafting and ease of implant placement on a 10-point scale showed no statistical differences (8.78 vs 8.27, p = 0.2355; 8.05 vs 8.75, p = 0.1118, respectively). Conclusions A porcine dentin-derived bone graft material has clinical safety, tolerability, and performance for implant placement at 4 months after tooth extraction at least as good as a commercial bone-derived material. Clinical relevance The availability of porcine dentin-derived bone graft material allows wider use of dentin-derived material which has so far only been available in the form of autologous dentin from the patient’s own teeth.
