Adhesive Dentistry: Materials & Techniques Simplified
Biologic Width Adjacent to Loaded Implant with Machined and Rough Collars in the Dog
Dental implant surface technology has evolved from a relatively smooth machined implant surface for osseointegration to more roughened osteoconductive surfaces. Recent studies suggest that peri-implant soft tissue inflammation with progressive bone loss (ie peri-implantitis) is becoming a prevalent condition. One possibility that could explain sucha a finding is that more bacterial plaque forms on the roughened implant and abutment surfaces, which may result in the peri-implant inflammation if the soft tissues. This study compared 36 tissue-level implants with a machined transmucosal collar to 36 implants with a relatively roughened transmucosal surface in the dog. The results demonstrated that the connective tissue contact was similar between the two implant types but that the junctional epithelium and biologic width dimensions were greater around the implants with the machined collars...
Oral Soft Tissue Laser Ablative and Coagulative Efficiencies Spectra
The key to the success of soft tissue
lasers is their ability to cut and coagulate the
soft tissue at the same time. Present work is
aimed to derive the wavelength-dependent
differences in photo-thermal ablation and
coagulation efficiencies for oral soft tissue
pulsed dental Near-IR Diode, Mid-IR Erbium
and IR CO2 lasers. Even though the soft tissue photothermal
ablation has been extensively
studied, there remains a discrepancy
between (a) the widely proliferated notion
about efficient Near-IR 800-1,100 nm laser
ablation of the oral soft tissue, and (b)
studies reporting the inefficient soft tissue
Near-IR absorption/ablation. Indeed, the notions about “the key to
the usefulness of the Nd:YAG is that this
wavelength is highly absorbed in oral soft
tissue”, and “all currently available dental
laser instruments and their emission wavelengths
have indications for use for incising,
excising... oral soft tissue surgery”,
contradict an observation illustrated here...
The Management of Immediate Implant Placement to Optimize Aesthetic Outcome in the Anterior Maxilla
Following tooth extraction the implant surgeon may select between various implant placement timing and loading protocols. Ideally these are to be determined prior to extraction, be it immediate, early, or late placement. Immediate implant placement even in the aesthetic zone is a literature supported treatment modality with success comparable to alternative placement protocols. Meticulous restorative treatment planning of a tooth destined
for extraction is essential. Selecting the appropriate implant and techniques may preserve and ensure natural aesthetics. Utilizing the patient’s own tooth crown can better provisionalize the implant with a ‘walk out as you walk in’
Immediate Placement of Dental Implants in the Esthetic Zone: A Systematic Review and Pooled Analysis
Research interest on immediate placement
of dental implants has shifted from implant survival toward
optimal preservation of soft and hard tissues. The aim of
this study is to systematically assess the condition of implant survival, peri-implant hard and soft tissue changes, esthetic outcome, and patient satisfaction of immediately placed single- tooth implants in the esthetic zone. A pooled analysis was performed to identify factors associated with survival and peri-implant tissue changes after immediate implant placement. Immediate placement with immediate provisionalization of dental implants in the esthetic zone results in excellent short-term treatment outcome in terms of implant survival and minimal change of peri-implant soft and
hard tissue dimensions.
