“…Eight of the selected studies [ 3 , 15 , 21 – 25 , 27 ] evaluated the survival rates in relation to the type of collar surface characterization. Radiographic evaluation of MBL was performed by means of periapical radiographs in 9 studies [ 3 , 15 , 20 – 24 , 27 , 28 ], panoramic radiographs in two studies [ 19 , 25 ], and maxillofacial CT in one study [ 26 ]. Rough and machined collars were considered in 7 studies [ 15 , 20 , 21 , 23 , 24 , 26 , 28 ]; while machined and microthreaded neck implants were installed in seven studies [ 3 , 15 , 19 , 21 , 22 , 24 , 25 ].…”

Background. It is important to understand the influence of different collar designs on peri-implant marginal bone loss, especially in the critical area. Objectives. The purpose of the present systematic review and meta-analysis was to compare dental implants with different collar surfaces, evaluating marginal bone loss and survival rates of implants. Methods. Eligibility criteria included clinical human studies, randomized controlled trials, and prospective and retrospective studies, which evaluated dental implants with different collar surface in the same study. Results. Twelve articles were included, with a total of 492 machined, 319 rough-surfaced, and 352 rough-surfaced microthreaded neck implants. There was less marginal bone loss at implants with rough-surfaced and rough-surfaced microthreaded neck than at machined-neck implants (difference in means: 0.321, 95% CI: 0.149 to 0.493; p < 0.01). Conclusion. Rough and rough-surfaced microthreaded implants are considered a predictable treatment for preserving early marginal bone loss.

“…Different implant neck designs have been proposed in order to stabilize the bone-implant contact [ 19 , 20 , 26 , 29 , 37 ]. The smooth neck implants result in reduced plaque accumulation and thus presumably prevent peri-implantitis [ 15 , 16 , 22 ].…”

“…13 However, researchers gradually discovered that the machined necks led to crestal bone loss during early functional loading after several decades of installation procedures. [14][15][16][17] Additionally, some scholars reported that the micro-roughened surface did not increase plaque accumulation, nor did it lead to crestal bone loss; however, the surface was reportedly more conducive for forming a wide and tightly attached closed loop of connective tissue. [18][19][20][21] Therefore, the suitability of machined and micro-roughened surfaces for the transmucosal area is currently debated.…”

Modifying the surface of the transmucosal area is a key research area because this process positively affects the three functions of implants: attachment to soft tissue, inhibiting bacterial biofilm adhesion, and the preservation of the crestal bone. To exploit the potential of titania nanotube arrays (TNTs) with or without using bovine serum albumin (BSA) to modify the surface of a dental implant in contact with the transmucosal area, BSA was loaded into TNTs that were fabricated by anodizing Ti sheets; the physical characteristics of these arrays, including their morphology, chemical composition, surface roughness, contact angle, and surface free energy (SFE), were assessed. The effect of Ti surfaces with TNTs or TNTs-BSA on human gingival fibroblasts (HGFs) was determined by analyzing cell morphology, early adhesion, proliferation, type I collagen ( COL-1 ) gene expression, and the extracellular secretion of COL-1. The results indicate that early HGF adhesion and spreading behavior is positively correlated with surface characteristics, including hydrophilicity, SFE, and surface roughness. Additionally, TNT surfaces not only promoted early HGF adhesion, but also promoted COL-1 secretion. BSA-loaded TNT surfaces promoted early HGF adhesion, while suppressing late proliferation and COL-1 secretion. Therefore, TNT-modified smooth surfaces are expected to be applicable for uses involving the transmucosal area. Further study is required to determine whether BSA-loaded TNT surfaces actually affect closed loop formation of connective tissue because BSA coating actions in vivo are very rapid.
