Abstract
Discussion Forum (0)
The following report summarises the second paper presented during the Consensus Conference 2015 session, at the EAO's 24th annual Scientific Meeting in Stockholm, 2015.
The literature search aimed to provide an overview of computer-supported implant planning and guided surgery from examination to planning and execution, including possible errors and pitfalls, in order to justify the indications for guided surgery. The conclusions are:
- guided implant surgery clearly reduces inaccuracy as compared with freehand surgery
- the accuracy obtained when following guided implant surgery protocols increases the possibility of delivering an ideal final reconstruction
- transferring the implant planning data to the operative field remains the most difficult part
- tooth-supported guides render the highest accuracy and mucosa supported guides offer higher accuracy than bone supported guides (Figure 1)
- future improvements may come from reducing the steps needed for guided surgery
- if the predictability of the treatment can be increased, the number of clinical implications can be further expanded
- as guided surgery adds precision to flapless surgery, it has implications in geriatric as well as medically compromised patients
- stress reduction in the operating room as a result of guided surgery may be a considerable additional benefit
- computed tomography (CT) does not offer advantages over cone beam computed tomography (CBCT) regarding guided implant surgical procedures
- the clinical situations and the categories of patients who benefit the most from guided surgery should be identified more clearly

Having identified and summarised the available literature related to CAD/CAM-fabricated implant-supported restorations, promising short-term results have been observed (Figure 2). Overall, the current evidence is quite limited due to the quality of studies and the paucity of data on long-term clinical outcomes.
Digital technology is used for the design and manufacture of implant prosthetic components, specifically for abutments, crown and bridge frameworks and associated veneers. Clinical feasibility has been demonstrated for most of them, offering technical, clinical and procedural benefits. No information is presently available on monolithic reconstructions made entirely using CAD-CAM procedures.
In many clinical situations, computer-aided reconstructive dentistry can offer specific benefits relating to standardisation and data acquisition, communication tools, and industrialised fabrication with a reduction in time, efforts and costs.
But there are important research implications: the rapid development of CAD-CAM technologies has added a multitude of new parameters to be tested, and researchers have to identify the most relevant clinical questions and the appropriate control groups. From the point of view of evidence-based dentistry, the authors recommend further studies designed as randomised controlled clinical trials and reported according to the CONSORT statement.
Diverse digital imaging devices (Figure 3) have recently been introduced allowing precise and reproducible assessment of implant-related outcome parameters, and therefore a standardisation of the results.
Optical scanning is being used for the 3D assessment of changes in the soft tissue contour. The combination of an optical scan with preoperative CBCT allows the determination of the implant position and its spatial relation to anatomic structures.
Spectrophotometry is commonly used to assess the colour match of prostheses and peri-implant mucosa to natural dentition and gingiva.
When available, multiple patient-related data sets (e.g. CBCT, intraoral and laboratory scans, virtual planning of implants and restorations) should ideally be integrated to maximise their synergistic diagnostic value: the so called 'virtual patient'.
Regarding research on this subject, there is a need for validation and standardisation of the majority of the novel digital imaging techniques and dedicated software. At the same time, computer algorithms have to be improved to enable accurate matching of different 3D data sets (e.g. facial scan and CBCT) and integration into specific software. Research is required to validate these novel methods before they are used in daily clinical practice.
