One-Year Prospective Study of 7-mm-Long Implants in the Mandible: Installation Technique and Crown/Implant Ratio of 1.5 or Less

Abstract

This study prospectively evaluated the clinical prognoses of short implants (7-mm long) in the mandible. We investigated the clinical prognosis of short implants in 20 patients (46 implants) according to the installation technique (submerged or nonsubmerged), installation depth (5.5-mm depth, 7-mm depth), and crown/implant ratio. We investigated the marginal bone loss and peri-implant soft-tissue index 12 months after the final prosthetic delivery. Twelve months after prosthetic delivery, no statistically significant differences were observed in bone loss in relation to the type of installation technique, installation depth, or crown/implant ratio. The plaque index and pocket depth indexes were not influenced by the installation technique, installation depth, or crown/implant ratio. We observed marginal bone loss of 3.3 mm in 1 implant from the nonsubmerged group. The total 1-year success rate was 97.83%. Based on this 1-year success rate, short implants had a good clinical prognosis, regardless of the installation technique, installation depth, or crown/implant ratio.

Long-term Short Implants Performance: Systematic Review and Meta-Analysis of the Essential Assessment Parameters

“…summarized in Table 1. Among these selected articles, three were randomized clinical trials (8-10), two were prospective cohort studies (11,12), and the remaining eight were prospective studies (13)(14)(15)(16)(17)(18)(19)(20). The patients were majority treated at university settings (5 studies) or in private dental clinics (3 studies), but one study (17) has a multicenter approach, combining results from patients treated in an academic environment and two private offices.…”

“…Bone atrophy of the posterior mandible residual alveolar ridge presenting height and/or thickness limitations is a challenge for dental implant installation. Use of an appositional autograft (Penarrocha-Oltra et al 2014), interpositional autograft (Bormann et al 2010), distraction osteogenesis (Zwetyenga et al 2012), guided bone regeneration with membranes (Simion et al 2007a,b;Parrish et al 2009), lateralization or nerve transposition of the inferior alveolar bundle (Metzger et al 2006;Khajehahmadi et al 2013), and short implants (Kim et al 2013;Mezzomo et al 2014) are the most commonly used techniques for implantsupported rehabilitation in these areas.…”

Biomechanical investigations of the secondary stability of commercial short dental implants in porcine ribs

“…They stated that with a success rate of 98.9% and 98.2%, short implants can now be seen as a valuable treatment option in critical patient situations, which is what Kim et al [16] proved in their 1-year followup study as well.…”

“…The prepared specimen was installed in a self-developed biomechanical hexapod measurement system (HexMeS, Figure 3) [16], which has been designed especially to apply different magnitudes of force on a small object such as an implant. The system consists of three main parts: a hexapod high-precision robot (PI M-850.50; Physik Instrumente, Karlsruhe, Germany) to perform translations and rotations with high resolution ( < 1 μm, 5 μrad), thus applying forces and torques to a dental specimen; a high-precision three-dimensional force/torque transducer (ATI FTSGamma 130/10; Schunk Spannund Greiftechnik, Lauffen/Neckar, Germany) for force and torque measurements and an optical system for a precise position registration, consisting of an aluminium cube, equipped with three pin holes (diameter of the holes: 2 μm; Melles-Griot, Bensheim, Germany) and back-illuminated with a laser (35 mW, 658 nm; Laser 2000, Wessling, Germany); and three video The experimental procedure is described as follows.…”
