The guides were stored in three different environments: directly exposed to sunlight (S₁), in normal interior room conditions (S₂), and in darkness (S₃). The guides were digitally scanned immediately after fabrication and post-processing, and after 1, 3, and 6 months of storage. For each group, the mean deviation of the root mean square (RMS) between guide's intaglio surface, as well as the axial deviation between sleeves' housings were calculated.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The mean axial variations of angular axis deviation of sleeves' housings ranged between 0.09° and 3.99°.

Demographic data, diagnostic information and linear measurements were extracted from patient files and CBCTs. The feasibility of IIP, EIP and DIP was assessed for all cases by both authors, based on the following criteria: availability of apical bone, position of the tooth in relation to the morphology of the alveolar process, buccal bone morphology and presence of midfacial recession. The reasons for not being able to perform an approach, and the viable alternatives for each approach were secondary outcomes. DIP was considered to have been preceded by alveolar ridge preservation (ARP).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Ninety-two patients could be treated by means of IIP, EIP or DIP.

Fifty-two patients (95% CI: 42%–62%) could by treated with IIP, 58 (95% CI: 48%–67%) with EIP and 88 (95% CI: 80%–93%) with DIP. The feasibility proportions of IIP and EIP were significantly lower than the one of DIP (<i>p</i> &lt; 0.001). All patients who could be treated with IIP could also be treated with EIP or DIP. Lack of apical bone for implant anchorage was the main reason for not being able to perform IIP and EIP.
