  • 80-yr-old female presented with discomfort related to upper teeth.
  • About 10 years previously she underwent implant surgery in mandible & received temporary teeth immediately as bone density was sufficient for immediate loading
  • Patient requested treatment plan for upper arch that would give her immediate teeth
  • Patient had no discomfort or complaints related to mandibular implants
  • Plus, patient’s hygiene was very good for maintaining healthy peri-implant tissue
  • All remaining teeth were extracted
  • Some teeth had severe periodontitis & some had decay at cervix
  • Drilling up to 2.9 mm was conducted at each implant site & eight 3.5×15mm implants were placed using minimal flap
  • All fixtures showed excellent initial fixation & immediately-placed implants only had small socket defects
  • Eight fuse abutments were connected & flaps were sutured to create tight sealing against fuse abutments

Panoramic scan taken immediately after surgery

First premolar implant  showed some mis-fit between crown & ratio

  • Intraoral scans taken 2 months after surgery
  • Shadows of extraction socket can still be seen, but regenerated bone has started to fill socket defects
  • Fuse abutments are functioning well without any problem
  • Impression was taken for customized zirconia abutments
  • Panoramic & intraoral scans taken 3 months after surgery
  • Zirconia customized abutments were connected to each fixture
  • Socket defects are completely filled with regenerated bone even in the case of immediate loading on immediately placed implants
  • Zirconia customized abutments & PMMA temporary bridge made using CAD/CAM technique
  • Zirconia abutment is excellent for both esthetics & hygiene, as has less than 1/10 bacterial accumulation on surface compared with metals including titanium
  • PMMA provisional bridge is stronger than tooth resin, especially at margin, so beneficial for functional & occlusal tests
  • Full zirconia one-piece bridge
  • Patient was very satisfied & thankful for ‘teeth’ from beginning to end

How can primary stability be increased?

Primary stability is especially important in the case of poor quality bone. The instability of dental implants results in fibrous encapsulation and failed osseointegration (Lioubavina-Hack, et al. 2006). One method for increasing primary stability is modifying the surgical technique for implant placement. Studies have reported that the undersized surgical technique, which uses a final drill diameter smaller than the diameter of the implant, results in a higher primary stability when compared with the press-fit technique (Tabassum, et al. 2009, Tabassum, et al. 2010a).

Other studies have reported a higher implant stability with the bone-condensing techniques rather than the bone-drilling technique (Fanuscu, et al. 2007, Markovic, et al. 2011) and conventional techniques rather than the osteotome technique (Cehreli, et al. 2009, Padmanabhan, et al. 2010). The stress distribution of Ti implants with various thread depths has also been investigated using finite element analyses(FEA) to identify the most effective thread depth for stress distribution (Ao, et al. 2010, Chun, et al. 2002, Kong, et al. 2008).

The thread depth also provides a higher contribution than the thread width for stress distribution to the bone (Kong, et al. 2008).

Ti implants with a deeper thread depth provide a higher surface area, which is advantageous for increasing stability in areas of poor quality bone (Abuhussein, et al. 2010). Ti implants with deeper thread depths also facilitate an increased load and mechanical interlocking with poor quality bone.

Another method increasing the primary stability is to change the implant design, such as the shape of the implant body and thread, length, and diameter. Various thread designs for taper implants and other dental implant designs have already been reported to effect the primary stability. Taper implants also show a higher primary stability than cylindrical implants (Kim, et al. 2009, Sakoh, et al. 2006, Wilmes, et al. 2008).

Meanwhile, dental implants with a long length or wide diameter show a significantly increased insertion torque (Kim,et al. 2009, Wilmes, et al. 2008). Plus, dental implants without self-tapping blades have a higher primary stability than implants with self-tapping blades (Kim et al. 2011).

What is the ideal surface for dental implants?

Since the osseointegration concept was introduced by Branemark in the 1960s, primarily osseointegrated implants have been recommended in the dental treatment area and high implant success rates have been reported. A prerequisite for successful osseointegration is initial stability after implant placement, which depends on the surface characteristics and morphology of the implant and bone density of the surgical site.

Lately, various surface treatment methods have been studied to facilitate rapid and strong osseointegration. According to the surface roughness and topography, the surface chemistry plays an important role for osseointegration. Titanium (Ti) and Ti alloys are bioinert surfaces and are not able to directly bond with bone. One method for increasing surface reactivity is to coat the Ti surface with nanostructured calcium. Many in vitro and in vivo studies have already reported the effectiveness of nanostructured calcium coating.

For example, in vitro studies have reported that surface modification using calcium ions increased the growth of osteoblastic cells and promoted the precipitation of apatite on Ti surfaces in simulated body fluid. Plus, the effects of cell adhesion to calcium-incorporated Ti surfaces were reduced in human alveolar bone cells and MG-63 cells, and increased in human osteoblasts. Several in vivo studies have reported that incorporating calcium into Ti implants by hydrothermal treatment stimulated osseointegration by increasing the BIC % when compared with untreated Ti implants in rabbit models.

Various surface treatments

Surface treatment technology
guarantees an excellent result.

1. Nano bone matrix layer of Ca2+ -incorporated S-L-A surface
2. Fast & strong osseointegration
3. Dual check system for greater safety

Ca2+ is incorporated into the fixture structure to create a CaTiO3 nano-structure. This then forms a unique & uniform nano-structure with Ca2+ions, which activate osteoblasts in living organisms.
