implants_one-piece implants Ryc. 11 Ryc. 12 Today two main schools of implant surgery exist, with diferent procedures, some being in apparent contrast. Regardless of the technique adopted, the indispensable importance of x-rays is unquestionable, especially in the planning stage, and also for medical-legal reasons. Regarding our case studies, we can airm that in rehabilitation in immediate loading (as it is properly called) carried out, that is, with one- piece, emerging and strengthened implants, the alveolar bone reabsorption is radiologically less frequent than in the technique in deferred load- ing, at least according to check-ups after a set period of time. This should be considered mainly in relation to the distribution of functional stress in the contact zone between screws and cortical bone. Naturally, this observation does not allow us to automatically airm that in the same sub- jects even the long term radiological results (10- 15 years) will be better, but it gives us the right to legitimately consider this hypothesis. Even other elements of the classic technique in immediate loading using mono-structural, Fig. 11_A recent proposal: immediate loading on two-piece/component implants. The technique is still awaiting real/inal validation. Fig. 12_Peri-implant conoid reabsorption. Fig. 13_Biomechanical models with inite elements. a. Deferred loading. b.
