The incidence of various complications such as incorrect prosthesis, peri-implant mucositis, and peri-implantitis is high; premature loss of implants is encountered due to osteointegration process not being completed for some unexplained reasons. However, there is no study in the literature examining the nonfunctional period of implants. Closure screws of different implant companies have different designs like surface properties, and areas, where closure screws sit, are important reservoirs for microorganism colonization.

Definitive restorations were delivered after 2 months. Pink esthetic scores (PESs), vertical soft tissue alterations, and bucco-palatal ridge dimensional changes were measured and assessed using intra-oral digital scans at baseline and 1 year post-procedure.

No significant difference was reported in the baseline bucco-palatal ridge thickness between the two groups (&lt;i&gt;p&lt;/i&gt; = 0.6). After 1 year, the bone shielding group demonstrated 0.38 mm ridge shrinkage which was statistically significant (&lt;i&gt;p&lt;/i&gt; = 0.0002) compared to 1.67 mm ridge shrinkage in the DZ group. In addition, the average total PES in the bone shielding group was 12.04 versus 10.28 in the DZ group. No significant difference was reported in the mesial papilla length between the DZ and the bone shielding group after 1 year (&lt;i&gt;p&lt;/i&gt; &gt; 0.05). However, the midfacial gingival margin (&lt;i&gt;p&lt;/i&gt; = 0.026) and distal papilla were significantly higher in the DZ group (&lt;i&gt;p&lt;/i&gt; = 0.0025). There was no significant difference in the mean ± SD mm bone gain at the apical level between the two studied groups after 1 year (&lt;i&gt;p&lt;/i&gt; = 0.06) showing 0.85 ± 0.23 and 0.64 ± 0.32 mm, respectively.
