Small‐diameter titanium Grade IV and titanium–zirconium implants in edentulous mandibles: three‐year results from a double‐blind, randomized controlled trial

Abstract

After 36 months, similar outcomes were found between Ti Grade IV and TiZr implants. The results confirm that the results seen at 12 months continue over time.

One‐year clinical outcomes of locking taper Equator attachments retaining mandibular overdentures to narrow diameter implants

“…[17][18][19]27,29 These measurements were performed on the mesial, distal, buccal, and lingual side of the implants with the aid of a Goldman-Fox Williams probe.…”

“…[17][18][19]29 The measurements were performed in the mesial and distal faces, and the implant length was used as a control of the radiographic distortions. The images were analyzed using the DBSWIN Imaging software 4.5 (D€ urr Dental, Bietigheim-Bissingen, Germany) using the tools for linear measurements, and the external edge of the implant head was used as a reference point during the evaluation of the peri-implant bone level.…”

“…12 These clinical limitations, together with the continuous resorption of the alveolar ridge and significant decrease in bone volume, mainly in the horizontal sense, may limit the utility of standard diameter implants in this population in the absence of additional surgical techniques for bone regeneration. [17][18][19][20] According to the aforementioned clinical findings, NDI and MI are a safe treatment option for edentulous elderly patients with residual ridge atrophy. 14 NDI and mini-implants (MI) are indicated in cases with limited bone thickness, where less invasive and simplified surgical alternatives are required.…”

“…13,14 Different options have been proposed to overcome these limitations, such as narrow diameter implants (NDI). 21 Several studies [16][17][18][19]23 have been performed to clinically and radiographically evaluate the behavior of NDI as MO retainers. 15,16 A high predictability was demonstrated for both anchorage modalities.…”

“…14 NDI and mini-implants (MI) are indicated in cases with limited bone thickness, where less invasive and simplified surgical alternatives are required. However, these studies focused on the alloy type [17][18][19] used to manufacture the implants, the surgical type technique, 23 the loading type 22 used or the quantity of NDI 16 used to anchor the MOs. [17][18][19][20] According to the aforementioned clinical findings, NDI and MI are a safe treatment option for edentulous elderly patients with residual ridge atrophy.…”
