A Review of Surgical Bone Drilling and Drill Bit Heat Generation for Implantation

2022-11-01 , Islam M.A. , Nur Saifullah Kamarrudin , Ruslizam Daud , Mohd Noor S.N.F. , Azwan Iskandar bin Azmi , Zuradzman Mohamad Razlan

This study aims to summarize the current state of scientific knowledge on factors that contribute to heat generation during the bone drilling process and how these aspects can be better understood and avoided in the future through new research methodologies. Frictional pressures, mechanical trauma, and surgical methods can cause thermal damage and significant micro-fracturing, which can impede bone recovery. According to current trends in the technical growth of the dental and orthopedic industries’ 4.0 revaluation, enhancing drill bit design is one of the most feasible and cost-effective alternatives. In recent years, research on drilling bones has become important to reduce bone tissue damage, such as osteonecrosis (ON), and other problems that can happen during surgery. Reviewing the influence of feed rate, drill design, drill fatigue, drill speed, and force applied during osteotomies, all of which contribute to heat generation, was a major focus of this article. This comprehensive review can aid medical surgeons and drill bit makers in comprehending the recent improvements through optimization strategies for reducing or limiting thermal damage in bone drilling procedures used in the dental and orthopedic industries.

Quantifying the Impact of Drilling Parameters on Temperature Elevation within Bone during the Process of Implant Site Preparation

This study aimed to elucidate the influences of several drilling parameters on bone temperature during drilling, as excessive heat generation can cause thermal bone damage and affect post-surgery recovery. In vitro drilling tests were conducted on bovine femoral shaft cortical bone specimens. The parameters considered included tool rotational speed (s), feed rate (f), tool diameter (d), and drill tip angles of 118° and 135°. Drilling temperatures were studied across a range of 800–2000 rpm rotational speeds, 20–40 mm/min feed rates, and 2–4 mm drill diameters. A predictive statistical model was constructed using the response surface methodology (RSM). Analysis of variance (ANOVA) at a 95% confidence level (α = 0.05) revealed that rotational speed significantly impacted temperature increase, contributing to 59.74% of observed temperature rises. Drill diameter accounted for 16.21% of temperature variations, while feed rate contributed to 10.04% of the temperature rises. The study provides valuable insights into the predominant factors affecting bone temperature during drilling. Understanding these parameters and their interplay is pivotal for optimizing drilling conditions and minimizing potential thermal damage to bones.

Drill Bit Design and Its Effect on Temperature Distribution and Osteonecrosis During Implant Site Preparation: An Experimental Approach

2023-01-01 , Islam M.A. , Nur Saifullah Kamarrudin , Ruslizam Daud , Zuradzman Mohamad Razlan , Muhammad Faisal Hamidi @ Abdul Rani , Ibrahim ii

In this study, the drilling parameters will be evaluated to obtain optimal parameters in minimizing the impact of drilling damage on synthetic bone blocks. The effect of damage observed in the study is osteonecrosis that occurs in the drill hole for implant site preparation, where a smaller value is desired. The drilling parameters are optimized using the Taguchi method with two control factors: the feed rate and spindle speed; each parameter is designed in five levels. This experiment was then carried out on four different designs of drill bits, i.e., Twist (118°and 135°), spherical, and conical drill bits. While experimental planning uses L25 orthogonal arrays, the "smaller is better" approach is used as a standard analysis. The main findings of this research are 118° point angle twist drill bit is the ideal type of drill bit for bone drilling, as it produces less heat than other types of drill bits. The optimal range of feed rate and drilling speed for bone drilling is 40-60 mm/rev and 1000-1400 RPM, respectively. Combining these parameters helps to minimize heat generation during implant site preparation drilling.

Parametric investigation on different bone densities to avoid thermal necrosis during bone drilling process

2021-10-25 , Islam M.A. , Nur Saifullah Kamarrudin , Suhaimi M.F.F. , Ruslizam Daud , Ishak Ibrahim , Mat F.

Bone drilling is a universal surgical procedure commonly used for internal fracture fixation, implant placement, or reconstructive surgery in orthopedics and dentistry. The increased temperature during such treatment increases the risk of thermal penetration of the bone, which may delay healing or compromise the fixation's integrity. Thus, avoiding penetration during bone drilling is critical to ensuring the implant's stability, which needs surgical drills with an optimized design. Bovine femur and mandible bones are chosen as the work material since human bones are not available, and they are the closest animal bone to human bone in terms of properties. In the present study, the Taguchi fractional factorial approach was used to determine the best design of surgical drills by comparing the drilling properties (i.e., signal-to-noise ratio and temperature rise). The control factors (spindle speed, drill bit diameter, drill site depth, and their levels) were arranged in an L9 orthogonal array. Drilling experiments were done using nine experimental drills with three repetitions. The findings of this study indicate that the ideal values of the surgical drill's three parameters combination (S1D1Di2) and their percentage contribution are dependent on the drilling levels of the parameters. However, the result shows that the spindle speed has the highest temperature effect among other parameters in both (femur and mandible) bones.

A review of factors influencing peri-implant bone loss

2021-07-21 , Muhammad Ikman Ishak , Ruslizam Daud , Ishak Ibrahim , Fauziah Che Mat , Nurul Najwa Mansor

Dental implants report high survival rate for the treatment of patients with missing teeth and being one of the undeniable restoration techniques. However, peri-implant bone loss has recently arisen to be the highlight in contemporary implant therapy. Therefore, the possible causes that are detrimental to dental implants and surrounding tissues are important to be discovered. The present review focuses on the current etiologies of peri-implant bone loss and subsequent complications observed in clinical practices. A comprehensive literature search was conducted via PubMed, Scopus, and ScienceDirect databases using the related keywords. The literature reveals numerous etiological factors may initiate the loss of marginal bone in dental implant application: loading protocols, implant body placement, implant macro-design features, implant surface roughness, implantation site preparation, foreign body reaction, implant material particles detachment and contamination, and oral habit. Albeit the biomechanical, biological, or combination of factors are known to contribute in marginal bone resorption, the predictability of treatment modalities to handle the defect remains controversial and unclear. Further clinical trials and sophisticated quantitative assessment would be advantageous to help scrutinize the issue.
