In the past few decades, oral implantology has established itself as the most promising and successful means of oral rehabilitation after tooth loss. The reasons for the success of this treatment modality have been multifactorial. A few of these factors are greater understanding of bone anatomy, bone physiology, changes in implant macro design, modifications in surface treatments of dental implants, greater understanding of implant biomechanics, greater predictability of soft and hard tissue augmentations, and an enhanced understanding of the bone implant interface. Recent modifications in implant collar design including micro roughened collars and Laser-Lok have further helped in the maintenance of crestal bone levels. Emergence of newer concepts including platform switching, morse connection and elimination of microgap between implant-abutment junction have also favored implant dentistry.

It is also well understood today that "oral implantology is a prosthetically driven field with a surgical component." For long-term implant success, it is imperative that the treatment planning for the implant is based prosthetic protocols. Optimal implant placement favors the esthetic outcome of the restoration along with favorably directed occlusal forces. Screw loosening remains, one of the most common prosthetic complications after implant placement. This is commonly due to occlusal overload. To overcome these mechanical complications favorably directed occlusal forces play an important role in implant dentistry.

Present day implantology has witnessed the emergence of cone beam computed tomography (CBCT) which provides with an accurate three-dimensional (3D) visualization of the anatomic structures for an optimal selection of implant size. CBCT has already, become an established diagnostic imaging modality for various dental applications. These include endodontics, orthodontics, dental trauma, periodontal surgeries, and dental implantology.[1] In combination with interactive implant planning softwares, it also allows for virtual implant placement and prosthetic planning at a reduced radiation dose.

Another boon to implant dentistry has been the emergence of guided implant systems. The 3D information obtained by CBCT is used to virtually plan the implant dimensions, positions, and angulations. This information aids to fabricate drill guides so that the entire implant procedure can be planned with a higher precision and predictability. The guide systems currently available are classified into static systems and dynamic systems.[2] The static guide systems transfer the planned virtual implant positions through the stent in the anatomic regions. The dynamic stent systems have an additional advantage of computer navigation that can allow the surgeon to modify the plan if need dictates.

These advancements in imaging, stereolithograhy, and computer navigation has definitely increased the accuracy of implant surgeries and reduced complications to a minimum. A recent meta-analysis reveals that the variation between virtual planned implant positions and implants placed using stents have been reduced to 0.9 mm (mean error) at the point of entry and 1.3 mm (mean error) at the apex of the implant and a mean angular deviation of 3.5 degrees.[3]

I would like to conclude by drawing attention of the readers to a basic fact, that is, after years of advancements and evolution, it has been once again established that the ultimate success of implant dentistry lies in meticulous diagnosis and an accurate evidence-based treatment planning. The most important parameter is the correct case selection along with following of all principles of asepsis, optimum occlusal considerations and a due respect to both hard and soft tissue structures in proximity.
