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.
Diameter Selection of Implants Placed in Extraction Sockets: A New Approach
Implant placement in extraction sockets is considered a daunting challenge
due to offering risks of bone remodeling and consequent gingival alterations. Objective: This
study aims at proposing a protocol for selecting the diameter of upper anterior osseointegrated
implants placed in extraction sockets. This protocol was based on the bucco-palatal dimension of
the socket and allows a 3-mm gap to form between the implant and the outer surface of the buccal
bone wall. Such gap must be filled with biomaterial or autograft so as to increase the predictability
of long-term results.
Sinus Floor Elevation Via the Maxillary Premolar Extraction Socket With Immediate Implant Placement: A Case Series
When immediate implant placement is considered
for teeth with close proximity to the sinus floor, apical
extension of the osteotomy is significantly limited, and often
a staged approach is used. Implant placement into fresh extraction sockets and sinus floor manipulation using bone-added osteotome sinus floor elevation with implant placement
are techniques most often used independently or sequentially.
In this care report, immediate implant placement with simultaneous osteotome sinus floor elevation is an advantageous
combination of two successfully used techniques. This combined
approach can significantly reduce the treatment time
for implant therapy in teeth with close sinus proximity and provide the operator with the ability to place implants of desired length.
