Immediate implant placement by using natural bovine bone substitute and acellular collagen matrix

Adequate bone and soft tissue volume is important to allow proper implants osseointegration, survival and esthetic result. The aim of this case report was to observe an immediate implant placement by using natural bovine bone substitute and acellular collagen matrix to gain better soft tissue result. Upon screw-retained provisional bridge removal after four months, a successful peri-implant soft tissue healing was observed. Then one year after final bridge, a stable soft and hard tissue situation, as well as sufficient implant stability, granules osteointegration into newly formed bone was recorded

Immediate implant placement by using natural bovine bone substitute with hyaluronate

Sufficient bone volume is important to allow proper implants osseointegration. The aim of this case report was to observe an immediate implant placement by using xenograft granules with hyaluronate and without any membrane coverage. The augmentation areas were assessed 3 months later during final crown installation and after 1 year and 6 months of implant loading. Satisfactory implant stability, granules osteointegration into newly formed bone, as well as stable soft tissue supported by the granules were observed

Lactoperoxidase and human airway host defense

The lactoperoxidase (LPO) antibiotic system is a well-characterized component of mammary and salivary gland secretions. Because LPO has been shown to function in ovine airways, human airway tissue and secretions were examined for the presence of LPO and its substrate, the anion thiocyanate (SCN �). In addition, human airway secretions were tested for LPO-mediated antibacterial activity, and LPO’s activity was assessed against some human airway pathogens. The data showed that normal human airway secretions contained LPO enzyme activity (0.65 � 0.09 �g/mg secreted protein; n � 17), and Western blots of secretions demonstrated bands of the expected sizes for LPO. LPO mRNA was detected in trachea by sequencing PCR-amplified cDNA. SCN � , LPO’s substrate, was present in undiluted airway secretions at concentrations sufficient for LPO catalysis (0.46 � 0.19 mM; n � 8), and dilute
