Summary of "A Randomized Controlled Clinical Trial Comparing Conventional and Computer-Assisted Implant Planning and Placement in Partially Edentulous Patients. Part 3: Time and Cost Analyses."

This paper performed time and cost analyses and compared conventional vs computer-assisted implant planning and placement (CAIPP) protocols when placing single implants in partially edentulous patients. Partially edentulous patients were randomly allocated to one of three treatment groups: preoperative planning based on a conventional two-dimensional radiograph and free-hand implant placement (control [C], n = 26) or computer-assisted implant planning based on three-dimensional (3D) computer-tomography (test group 1 [T1], n = 24; test group 2 [T2], n = 23). A surgical guide was produced by stereolithography in T1 and by 3D printing in T2. In all patients, open-flap implant placement procedures were performed. Time and costs derived from each working step were recorded for each treatment protocol. Descriptive and analytic statistics were used to display the data and uncover differences between treatment groups. Overall office time was similar in all groups (C = 63.8 min; T1 = 77.2 min; T2 = 81.7 min). CAIPP and conventional protocols required similar times to perform the preoperative diagnosis, radiographic exam, and implant surgery. CAIPP protocols required longer surgical planning and template-production times. Overall economic costs were 31% (T1) to 20% (T2) higher for the CAIPP protocols due to the radiographic investigation and the surgical template production (C = Swiss francs [CHF] 1,567; T1 = CHF 2,268; T2 = CHF 1,946). In the present indication and methodologic set-up, computer-assisted protocols did not show an advantage over conventional protocols in terms of time or financial savings. The temporal and financial expenses should be put into perspective to potential benefits.

Medical and Biotech [MESH] Definitions

Work consisting of a clinical trial involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.

Work consisting of a clinical trial that involves at least one test treatment and one control treatment, concurrent enrollment and follow-up of the test- and control-treated groups, and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table.

Works about randomized clinical trials that compare interventions in clinical settings and which look at a range of effectiveness outcomes and impacts.

Works about a study where participants are assigned to a treatment, procedure, or intervention by methods that are not random. Non-randomized clinical trials are sometimes referred to as quasi-experimental clinical trials or non-equivalent control group designs.

Computer-assisted study of methods for obtaining useful quantitative solutions to problems that have been expressed mathematically.
