Sir,

Implant dentistry is considered a highly predictable treatment modality to replace missing teeth with implant-supported prostheses and is expected to play a significant role in oral rehabilitation in future. Dental implants today constitute an integral part of dental clinical practice for fully and partially edentulous patients because of its significant functional and biologic advantages as compared to conventional fixed or removable prostheses. Implant therapy also yields excellent long-term results, as documented by numerous 10-year studies with success and survival rates >95%.[1]

Uniform terminology and nomenclature for a profession are essential for effective communication, documentation, and for efficient searching in computerized databases using commonly accepted terms and keywords.[2] The lack of systematic terminology in dental implantology creates situation in which patient dental treatment records describing implant design, its specification, location, and prostheses may not be self-explanatory or is not available with patient, and the clinician is required to spend time on Internet or other sources to fully understand details of implant and prosthesis. The other situation may arise when a patient with multiple implants placed at different time duration report to same or other dental surgeon with inadequate treatment record making identification and location of placed implant difficult and time-consuming. Furthermore, many implantologists today use multiple implant systems as there is the availability of numerous implant systems in the market and this may complicate the identification of implant many years down the line. Management of implants late complications may include prosthetic replacement or implant removal which also requires information of implant system and details of other components. For patient chart documentation, case presentation, and communication with persons of same discipline, particularly with dental laboratory personnel and among those in different disciplines, it is necessary to use an accepted nomenclature as well as standardized abbreviations and signs.

At present, a great deal of misunderstandings occurs within the scientific community and between the different disciplines involved in implant dentistry in the absence of a universal implant identification and numbering system. A universal system will enable dentists, patients, and participating third parties to accurately identify a particular implant and historically record and follow its bioclinical status is thus the need of the hour. It should be simple to understand and teach, easy to pronounce in conversation and dictation, readily communicated in print and electronic transmission and easily adapted to standard charts used in general practice.[3] Implant identification system given by Colgan is less informative and does not give comprehensive information on implant and prosthesis.[3] Authors propose a Sharma and Jhingta dental implant identification, numbering, and nomenclature system as follows.

The system comprises seven components:

The first and second components involve the representation of the quadrant and tooth number as used in commonly accepted FDI (Fédération Dentaire Internationale) system of tooth numbering.[4] This gives information of implant location spatially in the quadrant and corresponding to equivalent natural tooth/teeth. The third component identifies the dental implant and differentiates from the natural tooth. “ǂ” symbol is used to represent an endosseous dental implant. The fourth component describes dimensions of dental implant, i.e., diameter and length of implant represented with symbol “Ø”. The fifth component describes the type of dental implant with the name of implant system and manufacture name. In addition, implant manufacturer reference card/warranty card may be attached to the patient record. The sixth component gives information about dental implant prosthesis. The seventh component is used for any additional information pertaining to dental implant or prosthesis- like implant type or implant connection or composition of prosthesis [Table 1].

For example:

  1. NobelReplace dental implant from Nobel Biocare is placed corresponding to maxillary right first molar with dimension of 5.0 and 11 mm and has screw-retained prosthesis, the representation becomes: 16ǂ Ø5 × 11 Replace select, Nobel Biocare, screw retained
  2. NobelReplace dental implant from Nobel Biocare is placed corresponding to position between maxillary right first molar and right second premolar with dimension of 4.3 and 10 mm and has all ceramic cement-retained prosthesis, the representation becomes: 15–16ǂ Ø4.3 × 10 Replace select, Nobel Biocare, cement-retained, all ceramic.


The proposed implant identification and numbering system provide detailed yet systemic information about the implant. The system is easy to use, learn, and communicate. Its universal acceptance and use will ensure a uniform method of communication and reference with regard to dental implants and associated prosthesis.
